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.
