I Was a Zombie for the F.B.I.

In the stormy night skies over 1950s America, their diabolical plan begins: a UFO invasion that will turn the world's population into zombies using deranged escaped convicts The Brazzo Brothers, a flying alien ZomBall, and the secret formula to our country's favorite soft drink. Now the FBI's toughest team of agents must infiltrate the alien army, destroy its body-snatching leaders and restore good-tasting carbonated beverages to a thirsty nation.
