It’s summer 1983 in a northern California suburb, and teenagers George, Hector, Paul, and Andy have been killing time the usual way: ducking their parents, tinkering with their bikes, and racing around town getting high. Just another typical summer break in the burbs—until Andy’s bike is stolen by the town’s legendary petty hoods, the Arroyo brothers. When the boys break into the Arroyos’ place in search of the bike, what they find is a crank lab. Being the kind of kids who rarely know better, they take a stash of crank to sell for quick cash. But in doing so they unleash hidden rivalries and crimes, as well as the dark and secret past of their town and their families.
