Gary Sparrow is a somewhat disillusioned TV repairman, in a drab marriage with his ambitious wife Yvonne, and best friends with Ron, a printer whose marriage is on the brink of breakdown. While on a TV repair call-out in East London, Gary accidentally discovers a time portal which leads to war time London. There he meets Phoebe, a pretty barmaid who works in the Royal Oak pub, and Reg Deadman, a dim-witted but friendly policeman.
Gary strikes up a friendship with Phoebe, and makes repeated trips through the time portal, gradually establishing a second life for himself in the 1940s. In this life, he claims to be both a secret agent (aided by his knowledge of future wartime events) and a singer-songwriter, in fact passing off modern day pop songs as his own, particularly songs by The Beatles. He impresses Phoebe by bringing her goods which are widely available in the present day, but were rationed in wartime Britain, such as chocolate, bacon, and nylons and they begin a romance.
I love it, great comedy, great nostalgia, great acting, perfect mix of characters!
