Plot

The best of British humor is on display in this satirical cold war romp! Donald Sinden plays Lieutenant Green, a radar expert in the Royal Navy. One night, whilst under the influence of alcohol, he welds an old pram to the deck of a foreign destroyer for a joke. The next morning, British Intelligence is desperate to know what the enemy’s new weapon is. To cover his tracks, Green calls it the ‘998’. When he is posted to the destroyer to explain about radar techniques, Green soon realizes that his prank has gone too far.
