Paul Groves, a television commercial director, takes his first dose of LSD while experiencing the heartbreak and ambivalence of divorce from his beautiful but adulterous wife. He starts his trip with a "guide", John, but runs away and abandons him out of fear.
Experiencing repetitive visions of pursuit by dark hooded figures mounted on black horses, Paul sees himself running across a beach.
As Paul experiences his trip, he wanders around the Sunset Strip, into nightclubs, and into the homes of strangers and acquaintances. Paul considers the roles played by commercialism, sex, and women in his life. He meets a young woman, Glenn, who is interested in people who take LSD. Having learned from Paul recently that he would be taking LSD, she has been looking out for him. Max is another friendly guide to his trip.
Glenn drives Paul to her Malibu beach house, where they make love, interspersed in his mind with a kaleidoscopic riot of abstract images intercut with visions of pursuit on a beach. Driven into the surf by his pursuers, Paul turns and faces them, and they reveal themselves to be his wife and Glenn.
As the sun rises, Paul returns to his normal state of consciousness, now transformed by the trip, and steps out to the balcony to get some fresh air. Glenn asks him whether his first LSD experience was constructive. Paul defers his answer to "tomorrow."
