Seven years ago, a nuclear bomb hid everything in Raccoon City in history. Seven years later, in the Midwestern city of Haverville, Senator Ron Davis was trapped at the airport due to a mass protest against his relationship with Wefamar. Just as he was getting dressed and preparing to leave, a protester bit the senator's guard to death. The protester turned out to be infected with the T virus! Claire Redfield, a survivor of the "Raccoon City Incident", rescued the congressman by chance, but at this time a plane rushed into the terminal. The people who pushed open the door were actually infected with the T virus! The government quickly took countermeasures, and Leon S. Kennedy, another survivor of the "Raccoon City Incident", was ordered to come to support. Will the tragedy of Raccoon City happen again? What kind of conspiracy is the mastermind behind the incident planning? The full CG movie "Resident Evil: Deterioration" adapted from the game will give the answer.
