Cold Blood

Lucy is a serial killer. She kills once a month. She kills her lovers.
Each time she kills, she leaves her victim in wild and lush forests. For nature to feed off.

Lucy is quite fond of the new boy and the same goes for him. But when Lucy takes him out for the day everyone doubts that he is coming back...
