In a small English village everyone suddenly falls unconscious. When they awake every woman of child bearing age is pregnant. The resulting children have the same strange blond hair, eyes and a strong connection to each other.

Featuring performances by popular artists of the 1960s, this concert film highlights the music of the 1967 California festival. Although not all musicians who performed at the Monterey Pop Festival are on film, some of the notable acts include the Mamas and the Papas, Simon & Garfunkel, Jefferson Airplane, the Who, Otis Redding, and the Jimi Hendrix Experience. Hendrix’s post-performance antics — lighting a guitar on fire, breaking it and tossing a part into the audience — are captured.
