Colette, lovely and vulnerable prostitute, accepts to take care of her unknown colleague's boy. She, herself, needs a child to make her loved ex return to her. So she's having two problems to solve at one time - to find a suitable "father" of her kid and to get off hand of Billy. Meanwhile, the relationship between Colette and Billy is developing, you just don't know in which way. Then, when she cannot get rid of Billy and realizes her ex has another women, the things between "Billy et Colette" are now quite transparent. Written by Martin Fritsch
