During a meteor shower, Barry's sister Brooke is attacked in her Bulla, Victoria studio by her model and her assistant, who have suddenly become zombies.

Barry asks Chalker to take him to Brooke's studio, unaware that a paramilitary group has taken her captive in the back of a truck that serves as a mobile lab for mad scientist Doc.

The two drivers, after revealing that those with an A negative blood type are not affected by the disease, offer to lead Barry and Benny to Brooke, who they claim is in custody nearby.
