King of Gamblers, Yan Kun and King of Deception, Long Tingguang, both set their eyes on Coral Island - an undeveloped empty island- for their future casino landmark. Through underhanded methods, Long wins the gambling match with Yan and thus acquires the rights to the island. Yan is then forced to blind his own eyes, while his wife is made to commit suicide, leaving Yan's five-year-old son an orphan.

18 years later, Yan's son has grown up as Lin Jianfei. His happy-go-lucky attitude is a cover for his ultimate goal: to avenge his parents' misfortunes. His gambling skills draws the attention of Long's enemy, Qiu Huaifeng. She hires Lin to work for her family's casino and Lin uses this opportunity to perfect his gambling skills.

Later, Lin and his friend, Xiangnan, are mistakenly arrested for illegal gambling by policewoman, Luo Qifang. Qifang and her sister, Wenxin, both turn out to be Lin's neighbour. Over time, the bickering pair become romantically involved, and Lin reveals his true identity as Yan Fei, the son of the King of Gamblers.

Just as the young couple's relationship blooms, Qifang discovers that she is actually Long Jiajia - the long lost daughter and the only surviving child of Long, Yan Fei's arch enemy.^[2]
