Sadobabies: Runaways in San Francisco (1988) follows a group of San Francisco street kids who occupy the vacant Polytechnic High School and make miniature dolls of themselves. Nancy Kalow shot the film singlehandedly on 8mm video between 1986-1988.
The whole film is available to stream at Folkstreams.
A follow-up film was made five years later, called The Losers Club, which caught up with those who were still around.
