Pet is a psychological-horror film about a man who has been rejected one too many times. Dominic Monaghan (The Lord of the Rings, Lost) plays Seth, a guy who just wants someone to reciprocate his feelings of love. The closest thing he has to this are the dogs at the shelter he works at. He takes care of them and in return they are eager to love him back. One day while he is eating at a diner he meets a beautiful waitress, one that finds her way into his heart in a matter of seconds. However, when Seth tries to coerce her into a date he lays it on too thick and comes off creepy. She repeatedly but politely denies him. Seth takes this as an insult and the final straw, so he begins to come up with a plan to capture the waitress and subdue his loneliness permanently. He decides to use an old forgotten area of the pound to serve as his prison. Soon she will become his pet and she WILL learn to love him!
