From The Dead Of Night

The moon is full and the night is alive with the un-dead walking the streets of Devastation, Texas. After a train accident unleashes an experimental chemical that is able to bring dead organisms to life, the unthinkable happens. The dead rise from their graves on Halloween night, escaping from a century-old cemetery hidden by time. With a taste for human flesh, the corpses descend upon a local high school named Resurrection. Now the only thing standing between the mutated ghouls and total destruction of the town is a small group of custodians working the graveyard shift in the bloody chiller.
