Rappers Snoop Dogg and Wiz Khalifa team up to create a modern-day Cheech and Chong. Devin (Khalifa) is a nerd who wants to graduate first in his class to keep his girlfriend happy. Mac (Snoop Dog) is a 15-year senior whose weed obsession keeps him from graduating, until he meets a hot new substitute teacher who won't put out until he gets out of high school. Fate causes Mac and Devin's worlds to collide, resulting in the ultimate stoner comedy with a star-studded hip-hop soundtrack.
