Bob Ho is an operative of the CIA as an undercover agent on loan from the Chinese Intelligence, who decides to retire after putting Russian terrorist Anton Poldark behind bars and falling in love with his next door neighbor Gillian, who has three kids from previous relationships: Farren (a step-daughter), Ian, and Nora. All of them think Bob works at a pen-importing company.

One day, Gillian leaves to visit her father in Denver, Colorado, and leaves Bob to take care of the kids. However, Farren and Ian despise him and plot to get rid of Bob. Using technology from the CIA, Bob takes control and bonds with the kids. Bob's partner, Colton James, informs him that Poldark has escaped from jail, and they suspect a mole in the CIA. Colton sends a file to Bob's computer for a formula for an oil-eating bacteria Poldark is working on. While snooping around Bob's house, Ian downloads the file, which he mistakes for music, onto his iPod. Poldark discovers the download and sends some of his henchmen to Bob's house, but Bob overpowers them.

After the attack, Bob and the kids hide at a Chinese restaurant, where Poldark's teenage henchman, Larry, tries to kill Bob. Bob defeats him and tells the kids about his job. His boss, Glaze, then arrives and demands the downloaded file, revealing himself to be working for Poldark. Bob knocks out Glaze, then hides in a hotel with the kids. Eventually, Farren tells Gillian over the phone about Bob's secret. As they wait, Farren holds out hope that her biological father will come back to get her so that she can have a "real family". Bob tells Farren that family is more than just sharing blood ties with someone, revealing that he never knew his birth parents and was raised in a group home. Farren then realizes that her father is not coming back and accepts Ian and Nora as her siblings. Fearing for her children's safety, Gillian flies home to take them back and angrily breaks up with Bob
