It's a Hollywood horror battle when werewolves Jack and Richard fight two vampires on a film set!
On what appears to be a moonscape, the Werewolf struggles against two vampires, Louis Belski and Liza Pyne.
Flashback to earlier that day: after reading the ransom note about his sister, Lissa, kidnapped by the Committee, Jack Russell's furious apartment manager Sandy and a repairman arrived to assess the damage to the place. Soon, neighbor Raymond Coker pulled Jack into a stairwell for a private talk about their shared curses as werewolves. Punches were thrown, but they parted with the issue unresolved.
Later, Jack received a frantic call from his actress friend, Clary Winter, begging him to rush to the movie studio. He went, unaware that Coker followed him. While chatting at the studio gate, the guard informed Jack that the missing actors Belski and Pyne had been found dead (unknown to Jack, the two, victims of Dracula, would soon awaken in a morgue as vampires). When Jack found Clary, she told him she'd found in a prop room a trunk belonging to Geraldo Kabel, a lawyer Jack's been searching for. They opened the trunk, which was full of occult objects, just as the full moon rose, and Jack transformed. Clary ran in terror, as the Werewolf followed, but he instead found himself on a moonscape movie set, where he was set upon by the two vampires.
Now, as the Werewolf is about to be bitten, the transformed Coker leaps into the fray. Despite at first mistaking Coker's entry as an attack on him, the Werewolf joins forces with his "brother" wolf to stake the vampires using wood broken from the movie set. They then pass out from exhaustion.
When they come to in the morning back in their human forms, Jack and Coker examine the trunk, and find a mystic book. Within it, they find a cure for lycanthropy: killing a fellow werewolf under a full moon.
