The day after soon-to-be valedictorian Henry Burke (Matt Bush) takes a hit of the chronic for the first time, his school principal (Michael Chiklis) institutes a zero tolerance drug policy and administers a mandatory drug test for all students. Henry has two options: fail and lose his college scholarship, or team up with his stoner friend Breaux (Sean Marquette) to beat the system. They steal a high powered ganja from law student-turned-drug-dealer Psycho Ed (Adrien Brody) and spike the school’s bake sale brownies, getting the whole school—faculty included—completely stoned out of their minds. But with the student body getting higher and higher with every brownie, and a pissed-off Psycho Ed on their tails for stealing his stash, they must find a way to keep their half-baked plan from going up in smoke.
