Who's there ?

A black bird with a yellow beak stands on a windowsill, looking out through a four-pane window with open blue shutters, then turns its head and opens its beak as if calling. The scene cuts to a man with a wide, unsettling grin and intense eyes, wearing a red jacket over a plaid shirt, who slowly moves his head and mouth as if speaking or laughing, set against a plain indoor wall with a framed picture.
