Armed robbers Harry, Terry, and Joe die when the security van that they're robbing catches fire in the Kingsway Tunnel in London. Their widows–Dolly, Shirley, and Linda–find their husbands' schematics and decide to stage it themselves.

Ali is a young Egyptian screenwriter determined to succeed in London, where he has been a student. He loves the artistic and political freedom, the colours, the music, the individualism. But he has little money, his student visa is about to expire and he has been thrown out of his lodgings. And so Ali moves in with a succession of eccentric and colourful London flatmates: Mark, a photographer with a very individual style, Linda, a young, blonde, very sexy model and Marilyn Monroe impersonator, and Miss Stevenson who is convinced that Ali is the reincarnation of her long dead Egyptian lover.
