Ordinary salaryman Kei has ended up at rock bottom after falling in love with a call girl and spending his life savings trying to pay off her debts. Now living out of his car while hiding from loan sharks, he contemplates ending it all... But when he comes to, Kei finds himself saved by the men of Circus, a brothel that caters only to male clientele. Despite his despair, he clings to the lifeline they offer him, and it becomes more than just an opportunity to pay off his debts, but a strange and unexpected respite. Living and working alongside the other men, each trying to survive in their own way, Kei faces his new chance at life head-on, learning both the sweetness and ugliness of desire and love — for a night and for a lifetime.
