Tonight "The Golden Mouse Trap" is a crime scene sealed by the cops. Who stabbed young newcomer Patricia in the face? Her jealous workmate Lola? The pianist who might know her from before? The slick client with money to burn?

Patricia is the newest, hottest escort girl in a seedy club called "The Golden Mouse Trap" in Franco-era Madrid. On her first night she ends up stabbed in the face and the main suspect is an older, instantly-jealous co-worker named Lola. While she clings to life on an improvised operating room in the basement, a no-nonsense police inspector seals the club forbidding any of the patrons to leave and conducts an urgent investigation on the premises and into the wee hours of the morning.
