"Ahas"

The episode is a retelling of the urban legend about the human-snake hybrid said to live underneath Robinsons Galleria.

Troy's wife Adela is locked at Alegria Mall's department store dressing room and is killed by a snake creature. Troy suddenly wakes up after a nightmare about his wife’s death.

Fashion designer Iggy Moda is planning to organize an event culminating Alegria Mall's Silver Anniversary. To make the mall's anniversary very special, Iggy conceptualizes fashion collection and mall's new logo, but at the same time, thinks of reviving rumors about Alegria Mall's alleged half-human half-snake lurking somewhere deep in the mall which has been the reason of the disappearances of some shoppers. Sarah, the half-human half snake, looks out in the vent and sees Troy, in whom she fall in love and becomes obsessed. Along with the mall's 25th anniversary is Sandra Alegria's 25th birthday. Coming back from the United States, she welcomes the new members as part of the mall company's board of officers and as the head of the company. Sandra also denies the rumors circulating between her and her alleged twin snake sister.

A shoplifter steals clothes and items from the department store by wearing multiple shirts. A saleswoman picks up on her behavior and takes her to a dressing room, which she secretly locks. After she finishes putting them on in the dressing room, she hears trembling sounds and feels movement, and discovers a chamber. She is then killed by Sarah. After she kills the shoplifter, she tells her evil self that she met someone named Troy, but her evil self insists that she will never be loved because of her appearance. Troy strolls around the mall while still grieving and finding answers to his wife's disappearance until he finds himself in front of the department store where he last saw his wife. He tries to open the dressing room door where his wife last went to, but is stopped by the same saleslady who had locked the shoplifter inside.

Meanwhile, security guards and staff members check the premises as the mall closes. Janitor Mang Banjo takes his cleaning rounds to Sarah's chamber and nervously cleans the mess carefully and silently. Sarah calls him as he tries to retreat to the elevator. Mang Banjo carefully communicates with Sarah to avoid angering her, but Sarah becomes furious when she notices that he continues to avoid eye contact. Sarah turns the janitor around in front of her to make him face her, and he rushes to the lift. However, Sarah escapes with him, and the old man realizes that it was a trick. Mang Banjo immediately calls the twins' father Alberto, who then prepares a handgun to meet Sarah. Meanwhile, Jake sees Sarah in the dark in the department store wearing a dress, and recognizes her at first as Sandra. He runs away as he sees Sarah transform into a snake with arms, and is killed when Sarah catches up to him.

Alberto talks to Sandra about Sarah's escape from her chamber. Then he later tells her that he just wanted to have good luck; a witch doctor had handed him a vial containing medicine which could bring good luck to his mall business. He tricks their mother, Lourdes, into drinking the medicine concealed in wine, which results in her giving birth to Sarah and Sandra. Lourdes believes Sarah to be a curse and wishes her killed, but Alberto keeps Sarah under the mall's basement, due to his belief that she can bring good luck to the family and the business. Sarah was fed at first with animals, until she tasted human blood when a construction worker accidentally fell into the chamber. Sandra remembers visiting Sarah ever since their childhood until they said their goodbyes to each other. Alberto then plans to kill Sarah once and for all. Meanwhile, Troy returns to his house and gets a knife, plotting revenge to kill Sarah before returning to the mall.

Back at the mall, Iggy officially unveils his masterpiece, a statue resembling the alleged half-human half-snake as part of the anniversary. Alberto arrives and orders Iggy to remove the image, fearing that it will ruin the mall's reputation. Alberto, Sandra, and Mang Banjo hurriedly return to the chamber, hoping to stop Sarah from her evil plans. Sarah shows up and is glad, believing that Alberto returned to introduce her to everyone, especially Troy. Meanwhile, Troy separately enters the dressing room and finds the secret chamber. Meanwhile, Alberto argues with Sarah and that he despises her, and then Sandra steps into Sarah's view and the two briefly reunite. Alberto and Sandra continue to argue with her, telling her that she had caused chaos and that she needs to stop. Sarah becomes enraged when she realizes that she is not planned to be a part of the mall anniversary, and claims that Alberto became greedy. Alberto draws his gun and tries in vain to shoot Sarah as she transforms fully into a snake, and is captured when Sarah binds him by her tail. He is then thrown by Sarah and dies after hitting his head on a bathtub rim.

Taking advantage of the commotion, Troy stabs Sarah in the back of her lower snake body, enraging her. Sandra, Troy, and Mang Banjo hurriedly escape the chamber; the trio then warns Iggy and the board members to leave the mall before they seek shelter in a hardware store to find more weapons. At the store, Sandra learns from Troy that Sarah killed his wife. They return to the mall and Sandra goes alone to find Sarah, and tries to bargain with her to figure out a new life together. Troy attempts to sneak-attack Sarah with his knife, but she knocks him down and then swallows him whole. While in her snake stomach, Troy kills Sarah from inside and then cuts his way out using his knife, leaving Sandra heartbroken and guilty.

Also among the passengers are celebrity vlogger and television show host Tim, socialite father and son Macoy and Macky, baggage handling supervisor Carlos, and Jane, who is pregnant, along with her grandmother Juling. In the first class cabin are socialite Connie and married couple Brandon and Miranda. Passengers are welcomed by flight attendant Bryan and are accommodated by co-flight attendants Pamela and Karen. Karen suddenly bumps into Dave, her ex-boyfriend, and apologizes for their past, but Dave ignores her.

While the plane takes off, Juling insists Jane to pretend that she fell in love with a foreigner as soon as they arrive home, which later turns out that she fell in love with a creature and is the father of their baby "tiyanak". After the plane reaches its cruising altitude, Carlos instigates a hijacking, interrogating the crew in the flight deck in protest over the airline laying off employees as part of cost-cutting strategy and demands the airline wire money to compensate for the laid off employees. Connie overhears the chaos and hides in one of the lavatories only to find the couple doing a mile high club, whom she urges to calm down and stop their acts out of fear of being killed. Meanwhile, Jane gives birth to her baby creature and suddenly passes out along with the baby. The plane suddenly goes into a short turbulence and faints almost everyone on board, except for Juling, who dies. Unknown to them, the creature lurks out and scratches some of the passengers. Karen later overhears a conversation between Carlos and Pamela, which she realizes Pamela helps in making Carlos' plans succeed.

In the lavatory, Miranda fights with Connie until the tiyanak comes out of nowhere and kills Brandon, Connie, Miranda and the rest of the passengers on board one by one, including Pamela, Eli, Macoy and Macky and another passenger. The remaining passengers seek safety, except for Adam. Capt. Robert Francisco tasks Bryan and Officer Charlie to check on the situation on board. Meanwhile, Adam is strangled by the creature's umbilical cord while Carlos fights the creature with a gun and is killed by it. The creature attacks the flight deck and strangles the pilot. Karen, Bryan, Dave and the remaining passengers make a plan to safety as Tim and Bryan fly the plane after losing the pilots. Gino and Lovely discovers a bomb planted underneath the seats by Carlos which is ready to detonate. Karen finds the child on the floor and picks it up, while Dave throws it away from her before it transforms again into a tiyanak. Karen, Dave, Gino and Lovely run out to safety, but the creature traps Karen and Dave. Coincidentally, Iggy wakes up and is attacked by the creature.

After the flight lands safely, the creature attacks again and kills Lovely. Karen, Dave, Gino, Tim and Bryan escape the plane as it explodes, killing the creature. As the survivors tell their story to the authorities, Karen and Dave walk away together as the father of the creature vengefully appears behind them in the distance. After the credits, Iggy is shown to have survived the explosion.
