Return of the Living Dead: Rave to the Grave

The film opens a year after the previous film with Charles Garrison arriving at a mortuary with one of the canisters of Trioxin that he salvaged. He is greeted by a team of Government of Russia officials whose goal is to destroy the last of the canisters to avoid another incident. Nevertheless, one of them sprays three corpses with the gas, and revives them. Charles is killed during the incident, along with the mortuary owner and one of the government officials.
