In high school, Calvin Joyner was the golden boy, voted most likely to succeed, while Robbie Weirdicht was an overweight and easy target for bullies. After a cruel prank exposes Robbie during a school assembly, only Calvin shows him a shred of kindness. Fast forward 20 years, and Calvin, now an accountant, feels his life has not lived up to the promise it once held. On the eve of their class reunion, he receives a friend request from someone claiming to be a former classmate named Bob Stone. To Calvin's surprise, the once marginalized Robbie is now a muscular, confident man with a penchant for unpredictable behavior.

Bob reveals that he is in the CIA and enlists Calvin's accounting skills to help crack a case involving classified military secrets being sold to the highest bidder. As events unfold, the pair are thrust into a world of spy games and danger, dodging bullets and espionage while trying to stay alive. Although their reunion began under the pretense of needing an accountant, it becomes clear that Bob's reasons for approaching Calvin are more complex than they seem, and that Bob himself might be holding secrets. Trust becomes an issue as their adventure forces them to confront their pasts and re-evaluate what it means to be a hero in the real world.
