Prisoners of Gravity was a Canadian public broadcasting television news magazine program that explored speculative fiction — science fiction, fantasy, horror, comic books — and its relation to various thematic and social issues. Produced by TVOntario, the show was the brainchild of former comic retail manager Mark Askwith and writer Daniel Richler, and was hosted by Rick Green. The series aired 139 episodes over 5 seasons from 1989 to 1994.

After young Robert Graham commits a murder while drunk and defending his girlfriend, he is prosecuted by ambitious Mark Brady and sentenced to 10 years. Six years later, Brady becomes the prison warden and offers the beleaguered Robert a job as his chauffeur. Robert cleans up his act, but, on the eve of his pardon, his cellmate drags him back into the world of violence, and he faces a difficult choice that could return him to prison.
