Permissive

When Suzy arrives in London to visit an old friend, she is plunged into the ruthless world of the groupie, where she develops a cold, cynical instinct for survival. Mixing gritty location work, brooding flash-forward devices, and a soundtrack by cult prog rock legends Comus, Forever More and Titus Groan, Permissive is a grimly authentic countercultural experience.
