Stedanko (Stacy Keach), who are trying to bust an alleged drug kingpin named "Mr. Big", and discover a strain of marijuana that turns people into lizards, including Stedenko, who has been smoking cannabis to get inside the head of a drug user.

The film costars Paul Reubens and Evelyn Guerrero, and features small appearances by comedians Sandra Bernhard and Michael Winslow, and a cameo by Timothy Leary. Nice Dreams grossed $35 million, but it received mixed reviews.
