[2] Cheech & Chong are on a mission to siphon gasoline for their next door neighbor's car, which they apparently "borrowed," and continue with their day; Cheech goes to work at a movie studio and Chong searches for something to smoke (a roach), followed by him revving up an indoor motorcycle and playing extremely loud rock music with an electric guitar that disturbs the entire neighborhood.

The doped-up duo are expelled from the building and, in an attempt to find alternative means of income, start writing songs like, "Mexican Americans" and "Beaners."

Chong heads off to the hotel where Red is staying and arrives to find him in a dispute with the receptionist over how much the room is costing ("$37.50 a week, not a goddamned day!").

The receptionist is holding his luggage, consisting of a boom-box, a suitcase, and a 20-pound canvas bag full of high-grade marijuana hostage, and Red can't afford the bill.

After visiting the house of a girl's parents, whom they found at a music store on Ventura Boulevard, they all get into the parents' Rolls-Royce, light up a spliff, and drive to a stand-up comedy club where they tell jokes and encounter the angry hotel receptionist who was falsely arrested earlier that day and begin a commotion with him and a large female bouncer leading to a rally fight.

The "space coke" causes Cheech to go berserk and starts trashing their next door neighbor's house with a surprised Chong following after.

The film ends with the duo bursting through their neighbor's roof into outer space, achieving the ultimate high and Chong dropping the "space coke" back to Earth for others to try which leads to an animated sequence with Cheech and Chong ascending into a blunt which then takes off displaying the caption "That's It Man!"

The opening credits animated sequence was different from the theatrical cut, showing Cheech and Chong stealing their neighbor's car, which runs out of gas.

[5] Cheech and Chong are said to be running a teen center and playground, which is referenced throughout the television edit, and a sign for it is shown repeatedly as part of the filler material shot for this version.

The edit ends with an extended animated sequence in which Cheech and Chong fly into space to join Red on the spaceship and an extraterrestrial superhero plays guitar before turning into a dragon, and the Cheech and Chong Teen Center and Playground sign is shown one final time before the credits roll, as we hear Red laughing and asking, "ya get it?

The film was released on Blu-ray in 2017, containing the theatrical cut, trailer, radio spots and an interview with Cheech Marin.

"[25] Vincent Canby of The New York Times wrote that the film was "casual, slapdash and rude, and it's frequently hilarious in the way of some intense but harmless confrontation between eccentrics on a street corner.
