This extraordinary film follows the stories of three men who have had new or replacement penises constructed for them by surgeons.
It centres on Malcolm, who has lived with a penis hanging from his arm for the last six years. Malcolm's original penis dropped off 12 years ago and Malcolm had a new one made on his arm through a process called phalloplasty - ready to transfer to his groin.
But it never reached its final destination, leaving him with a penis dangling from his forearm. The film charts his long-term journey to recovery as he hopes it will finally be hung in the right place. The film also follows Anick, who was born intersex, with a micropenis.
Anick has spent his life undergoing surgery. He has a new penis pump fitted so he can achieve a pain-free erection. And then there is Lee, who was born in a female body but has undergone phalloplasty to change gender.
Through these men's stories, the film explores the process of phalloplasty, the psychological effects of being withoutone's manhood, andthe relationship between a penis and what it is to be a man.
