Have you ever thought someone was watching you . . . but there was no one there? 

One summer’s evening, Alice sees something out of the corner of her eye. She turns to look: just a trick of the light. She is no longer the lonely little girl she once was, with her games of make-believe and imaginary friend, Sam. 

Then Alice’s world is shattered in a tragic accident, and Sam creeps out of the shadows and back into her life. At first Alice is comforted by his presence: a best friend to help fill the void in her heart. Perhaps even help her find someone real to share her life with.

But Alice and Sam know he can only exist if she wants him there. So when Alice decides it’s time for him to leave, who will get hurt in order for him to stay alive?
