Convicts Peter Sellers, David Lodge and Bernard Cribbins, along with fake vicar Wilfrid Hyde-White, come up with a perfect jewel heist. The idea is that the convicts escape, effect their robbery, then return to the prison on an iron-clad alibi.
Unfortunately, tough new warden Lionel Jeffries throws a spanner in the works.
A simple plot is used to maximum effect in this quaint British caper comedy.
