It's Halloween night and Alison is giving a masked party in her mainson. At one point of the night she leaves her firends to go to the bathroom one moment...but two guys at the party follow her, hide and then frighten her with a scream for joke...but what they don't expect is Alison's reaction and skills in fighting/selfdefence....are you curious to see how Alison Halloween party m assacre's is going to end?
