Mrs Peel's Grand Hunt Ball invitation turns out to be a summons from Steed, and they set out to discover what's become of the world's most wanted criminals.
They're on the trail of Josino and follow him as he acquires a stuffed toy and a shaving cut. Steed takes the same path and ends up going back through time to 1790! Emma follows, much to the gang's surprise and confusion, and finds herself in the Tudor era after the mastermind cottons onto her. A leap across time saves Emma from the stocks and exposes Thyssen's fraud.
Another quirky and far out adventure for Mr Steed and Mrs Peel as they discover what is happening to world's top criminals - they end up in another century or do they? Grand set pieces, costumes and some neat chase of biker racing after Peel on the hill. The story is so balmy and is Peter Bowles' stammering character.
