Rats: Night of Terror

In the year 225 A.B. (After the Bomb), a group of post-apocalyptic bikers discover an abandoned research laboratory filled with food, water... and thousands of rats. But these are no ordinary vermin; these are super-intelligent mutant rodents with a ravenous appetite for human flesh. Can a bunch of heavily armed but not-too-bright human scavengers survive a night of terror against the most hungry and horrific predators on earth? (official distributor synopsis)
