The Goon Show, spearheaded by Peter Sellers and Spike Milligan, is one of the greatest comedy teams of all time. here, the classic radio troupe star in a hilarious caper involving a secret formula, an absent-minded professor, shifty crooks and the army.

Absent-minded Professor Purehart (Michael Bentine) loses his top secret formula in Harry's Grocery Shop. when Harry (Harry Secombe) tries to return it, he is mistakenly enlisted in the "Z" reservists under the command of a very whacky leader. What they don't know is some criminals have also enlisted and are now after the formula!
