The tale of two dimwitted brothers and what happens when the Virgin Mary asks them to

Two religious maniacs, Judas and Corned Beef, are visited by two aliens, Madeline Virbasius and Dion. Virbasius, dressed as the Virgin Mary, tells the two to kill people for Jesus and to drain the puss from their heads and bring it back to them. Fleming and Hammer set out to bring "the Virgin Mary" back as much puss as possible in a bucket.
