Jack Mook, a 22-year veteran member of the Pittsburgh Police Department, is a verified bachelor. In his leisure time, he helps at a local boxing gym, teaching impoverished children. He met his brothers, Jesse, 11, and Josh, 15, there.

They got along well, but when the two boys abruptly stopped appearing at the boxing facility, Jack went to search. When he discovered that kids were being mistreated in their foster home, he made a decision that changed their lives.
