I thoroughly enjoyed watching this on Netflix last night. The first part of the film presents archival footage of Camp Jened, a summer camp for young people with disabilities which was in operation from the 1950s to the 1970s. The second part of the film follows some of these campers as they become leaders in the disability rights struggles of the 1970s.
I watched this as an "alumnus" of the polio epidemic of 1952, but the film will be of interest to a broad range of viewers - especially those who have family or friends with physical impairments.
Addendum: The BBC has an excellent article about Judy Heumann, a disability activist featured in the movie.
