"The story follows a one-time bullied geek who grew up to be a lethal CIA agent (Johnson), coming home for his high school reunion. Claiming to be on a top-secret case, he enlists the help of the former "big man on campus" (Hart), now an accountant who misses his glory days. But before the staid numbers-cruncher realizes what he's getting into, it's too late to get out, as his increasingly unpredictable new friend drags him through a world of shoot-outs, double-crosses and espionage that could get them both killed in more ways than he can count."
