Plot title: Deliria Movie plot: Late at night inside a theater, a troupe of actors are rehearsing a musical about a mass murderer known as the Night Owl. When the show's leading lady Alicia sprains her ankle, she and the wardrobe mistress Betty sneaks out of the rehearsal for medical assistance in which the closest medical facility is a mental hospital. When speaking to the psychiatrist, Betty notices a imprisoned patient who is revealed to be Irving Wallace, a former actor who went insane and committed a killing spree. Unbeknownst to any of them, Wallace killed one of the attendants with a syringe and sneaked out of the asylum, hiding in the back of Betty's car. Once they arrive back at the theater, the director Peter fires Betty for leaving during rehearsal. As she packs her things and gets ready to leave, Betty returns to the car only for Wallace to murder her with a pickaxe. Moments later, Alicia then emerges from the theater upon the discovery of her friend's corpse. Later, police officers arrive to remove the scene and stations two officers in the parking lot to keep an eye on the premises.Meanwhile, the director creates an idea by altering the play's script; he renames the show's antagonist to Irving Wallace instead of an ambiguous killer, and insists that everyone stay the night to begin immediate rehearsals with the new material, resulting one of his actresses Corinne hide the theater's key so nobody can leave. With the promise of additional cash, the group reluctantly agrees.

While Alicia keeps searching for the key, Wallace arrives (with Peter thinking it's Brett) for the scene and strangles Corrine before stabbing her. Without the key's whereabouts, the group begins to panic and tries to contract the outside policemen. Wallace then... My question: How does Wallace kill Ferrari?
