Johnny Truelove is a young marijuana dealer living in Southern California. His father, Sonny, supplies him with marijuana, which Johnny distributes to his gang of friends, including Jake Mazursky, who owes Johnny a $1,200 drug debt. Mazursky makes a failed attempt at asking his father, Butch, and stepmother Olivia for the money. Meanwhile, Butch and Olivia are dealing with their rebellious teenage son Zack- Jake's half-brother. A fight breaks out between Jake and Johnny when Jake tries to pay Johnny only part of his debt. After back and forth retaliation, Johnny and his two henchmen, Frankie Ballenbacher and Tiko Martinez, go to confront Jake in person, but when they go to his house he is nowhere to be found. As they leave, they find Zack walking and decide to kidnap him with the intent of holding onto him until Jake pays his debt.
