Young Viscount Tony Pym wangles National Service leave on the pretext of standing as a Tory candidate for a local seat held by his family for generations. The request is a ruse to enable Pym to marry his wealthy American fiancee while she's still in England, but his masterplan backfires when he finds himself swept into an election campaign and beaten by Labour's Mr Cleghorn – who is then made a peer. In an attempt to save face, Pym decides to stand again – as a socialist. It all proves too much for the Pyms' loyal, true-blue butler, Mr Beecham...
