Cheech & Chong's Next Movie opens with the two aging stoners stealing gas in a trashcan, spilling it on themselves, and subsequently blowing up their car after trying to light a joint with gasoline fumes filling the vehicle. The rest of the film centers on Cheech wanting to get together with a social worker he likes, and wants the place to himself in order to seduce her. Another problem for Cheech is his cousin Red, who has just turned up from the stix and needs to be shown around town (Los Angeles). Cheech decides to kill two birds with one stone by sending Chong to meet his cousin.
