Willy (a 2D character in a drawing) is bored because he is playing alone in a paper. So he looks out from the paper and he sees Tony (a 3D character in a PC-monitor) who is playing tennis alone in a PC-monitor. After a little trouble, Willy and Tony are playing tennis together in the monitor. Just when Poly (a toy character), a police-toy, joins the game the artist returns home. It's a critical moment. Can they pass through the crisis?
