The Bully takes place in the present time in Upstate New York at a high school undergoing a remodel for a new boiler system. When the construction crew demolishes a block wall to make room for the new boiler, they discover a hidden room with a body strapped to a chair, gagged. When the detectives arrive, they soon find a note tucked in the black leather jacket and realize that this was a bully from the 1960s who disappeared in 1969. The detectives soon recruit a retired firefighter, Billy Sutter, who still lives in the neighborhood and remembers the bully and the events that took place then. Billy teams up with Jackie Summers, a new detective in training. While veteran detective Gerald Higgins and a rookie cop Johnny Wallace team up to interview students from a yearbook supplied by Billy.

The plot thickens when Billy is asked to accompany Jackie to Oregon to interview an old student who turns out to be Billy's high school sweetheart, Rose, whom he hasn't seen in over fifty-three years. The two soon realize the spark is still there between them after all the years apart. Love is in the air in this who done it love story where you think you know who done it. But there's a twist and a little bit of karma.
