Jackie and Luke Harrison are a divorced New York City couple who are struggling to co-parent their two children, daughter Anna and son Ben. Luke, an attorney, is living with his girlfriend of one year, Isabel Kelly, a successful fashion photographer several years his junior. Isabel, who has never wanted to be a mother, tries hard to make Anna and Ben feel comfortable. Anna repeatedly rejects her overtures while Ben, who likes Isabel, adds extra complications with his mischief. Isabel behaves with contempt tempered by caution around Jackie, believing she overcompensates for the divorce by spoiling her children.

Jackie, a former publisher turned stay-at-home mom, treats Isabel coldly, seeing her as an immature, selfish, overly ambitious career woman. She also continues to harbor malice towards Luke, as seen in confrontations about Isabel's parenting. After many arguments and hurt feelings involving Isabel, Jackie, and Anna, Luke proposes to Isabel, making her Anna and Ben's future official stepmother. This causes even more friction between the kids and adults respectively.

It's later revealed that Jackie has been silently battling lymphoma for some time, and the results of her latest scans say the disease is now terminal. She experiences a range of negative emotions, specifically jealousy of the woman who she feels is replacing her, and anger that after all of the sacrifices made for her children, she will never see them grow up. Jackie actively sabotages Isabel's effort to bond with the children, even to the point of refusing to allow Isabel to take Anna to see Pearl Jam and then later taking her to the concert herself.

Isabel and Anna's relationship eventually improves, and they bond over shared hobbies: music and painting. One day, after bringing back Ben from a birthday party, Isabel confronts Jackie, so she informs Luke and the children of her diagnosis, resulting in Anna emotionally storming out. That night, Jackie loosens up the tension by singing and dancing to "Ain't No Mountain High Enough" with Ben, soon joined by Anna too.

Both Jackie and Isabel continue to have disagreements, largely over Isabel's parenting. When Ben goes missing on Isabel's watch, Jackie threatens legal action and claims to have never lost him, which she later admits to be untrue. At school, Anna is consistently bullied by a boy she once liked and the two women give her conflicting advice, causing more tension.

Jackie later invites Isabel to have dinner with her, and they work out a shaky truce, coming to terms with Jackie's impending passing and Isabel's role as a stepmother. They bond when Isabel reveals her admiration of Jackie's maternal instincts, while Jackie in turn praises Isabel's hipness as a means to connect with Anna. Isabel finally lets her guard down when she tells Jackie her biggest fear is that on Anna's wedding day, all she will wish for is her mother's presence, while Jackie admits her own fear is that Anna will forget her. They come to understand that while Jackie will always have the children's past, Isabel will have their future, and the children can love them both without choosing.

On Christmas morning, the family gathers to celebrate together. Jackie, now largely bedridden, shares emotional moments with her children individually, telling them that she will remain with them as long as they remember her. Isabel takes a family portrait of Luke and Jackie with the children. Jackie demonstrates her acceptance of Isabel by inviting her to join them, stating, "Let's get a photo with the whole family." Isabel sits next to Jackie for the photo, with both women holding hands, finally at peace with each other.
