Directed by Ishiro Honda • 1963 • Japan
Starring Hiroshi Koizumi, Kumi Mizuno, Kenji Sahara

Leaving behind the kaiju genre for which he was best known, Ishiro Honda took a detour into hallucinogenic science fiction with this disturbing psychological survival thriller that stands as perhaps the director’s darkest and most complex work. When their yacht washes ashore a remote island, a group of vacationing youths soon find themselves giving in to the temptation of the strange mushrooms that grow there—initiating a grotesque transformation and descent into surreal terror.
