When his best friend, Nick the projectionist, gives him a magic ticket to the new Jack Slater film, Danny is transported into Slaters world, where the good guys always win. One of Slaters enemies, Benedict the hitman, gets hold of the ticket and ends up in Dannys world, where he realises that if he can kill Schwarzenegger, Slater will be no more. Slater and Danny must travel back and stop him.
