Grab a towel and get ready for the heat in Andrew Ahn's new film, Spa Night.

The Sundance favorite and Outfest selection follows David Cho (Joe Seo, who won the Special Jury Award at Sundance for his performance) a shy teenager who takes a job at a local Korean spa in Los Angeles that he soon discovers is a secret cruising spot for men.

Over the course of working night shifts at the all-men's spa he "begins to realize hidden inner desires that threaten his life as a dutiful son and student."

Director Ahn revealed his inspiration for the personal film:

"A few years ago, I discovered that some Korean spas in Los Angeles have been appropriated as a space for underground gay sex. A friend of mine told me over drinks in West Hollywood that he had a 'hot hook-up' with a guy in a Korean spa. This discovery felt both sacrilegious and thrilling at the same time. It is very easy for me to separate my identities. I can either be Korean or gay. Now, there is this place where I have to deal with my identities at the same time."

Spa Night premieres at Metrograph in New York on August 19 and will be released in L.A. on August 26.
