Plot

A group of hippies who live together in a communal apartment are arrested during a peace demonstration. Upon their release, they return home to discuss plans for another demonstration. That evening in a nightclub, the hippies watch as the mother of a young patron, Donna, arrives to take her home, in an effort to remove her from bad company. Sonny, one of the hippie group, passes Donna a note with the address of the communal apartment. Later at the apartment, a young woman experiences a bad LSD trip in which she "gives birth" to a huge egg. Donna arrives and is introduced to LSD during a musical ritual called "Om Pax Om." The next morning the hippies sell newspapers on a street corner. That evening Sonny and Donna go walking and encounter a gangster drug dealer and his friends, who proceed to beat up Sonny for refusing to become a dealer. The next day, after the second peace demonstration, the pushers wait in the alley for Sonny, and when he appears, they shoot at him but accidentally hit Donna instead. The group conducts a solemn procession through the streets carrying Donna's body.—Anonymous

The film is mainly plot less, following the daily activities of a group of hippies living in a communal apartment in Cleveland, Ohio. The hippies encounter hostile police at a peaceful gathering in a park, get arrested, and spend a night in jail. They earn money by panhandling and selling copies of an underground newspaper on the street. They stage a protest march against the Vietnam War on Cleveland's Public Square, discussing their viewpoints with random passersby. For recreation, they attend a rock concert at a local nightclub and frequently use marijuana and LSD ('acid'). Under the influence of LSD (illustrated by the filmmakers using various psychedelic effects), the hippies engage in nude dancing and uninhibited sex, and one girl experiences a bad trip.
