Satan announces his plans to throw a huge Halloween costume party on Earth at the W hotel, supposedly the Cecil hotel. Among other things, Satan decides upon a cake the size and shape of a Ferrari Enzo, which three notorious serial killers—Ted Bundy, Jeffrey Dahmer, and John Wayne Gacy—are entrusted with bringing to the party. Cardinal Roger Mahony and other Roman Catholic Church officials of Los Angeles, angered that Satan does not invite them to the party, plan to call the fire marshal the night of the party to complain, thus ruining it. When they are unable to do so after discovering that the fire marshal was also invited to the party, the clergy decide to crash it. However, Satan's security make sure they do not get in at all.
