A woman is strangled in the bath by a black-gloved killer who disposes of her body in a large trunk. The trunk is delivered to St. Hilda College, an exclusive finishing school. Betty-Anne, one of the female students, is strangled in the school cellar. The police, led by Inspector Durand, are called in to investigate. Suspects include La Floret, the voyeuristic gardener; Di Brazzi, the new swimming instructor; Mrs. Clay, the summer school French mistress; an old professor who collects birds; and a philandering young teacher called Richard. The murders continue but Jill, a keen amateur detective, helps the police identify the unlikely killer...

The film, set almost entirely in New York, tells of the life of some young people of the late Sixties: of the use they make of various drugs, including the terrible LSD, of their sex life and their freedom of costume and thought.

An elderly gangster just released from prison plans one last job, and gathers a small crew to do the job, but the plan goes sour when one of the crew betrays the details of the operation to a rival gangster.
