Sandi Toksvig goes behind the iconic green door of one of the most famous lesbian venues in the world, The Gateways Club in London. Starting off as a meeting place for bohemians, it became lesbian-only under the watchful management of the enigmatic Gina Ware and her sidekick Smithy until its closure in 1985. The Gates’ former clientele recount the many stories of love, heartbreak, friendship, scandal and sanctuary that played out in the club, including the venue's appearance in a Hollywood film. They open up the secret history of this haven for women, who could lose homes, jobs and children if their truth became known.
