2016 and a night in a gay sauna turns into a fight for survival, while a relationship of a different kind becomes heated on a night out in London’s Soho. In 1962 literary revelations strike two men sitting on a park bench speaking Polari and a 80s teenager time-travels into the future through his bedroom closet. Back to the present and London’s chemsex scene is put into perspective during one night at a chill-out party. While in 1976 sexual adventures await those who gorge on corduroy with his queer materials in Sir John’s Trouser Bar.

Sweat is the story of an afternoon of debauchery and intrigue as Simon takes leave of his senses and heads for a sauna. Negotiating the humiliating locker room strip where he inadvertently injures a fellow punter, he forges his first impromptu introduction to a handsome man called Tim. Nerves prohibit normal conversation as they share an empty sauna and both of the attractive men shy in each other's presence. Later, Simon encounters an opportunistic rent boy called Tiger and is amazed that at seventeen, he seems to have learned more about sex than Simon has in all his twenty-five years. Further into his journey, an experiment with poppers and some very public sexual displays, leave him wondering what he came for, and possibly leaving none the wiser, albeit with a phone number and a wry smile.
