Jim Wormold, an under-employed vacuum cleaner salesman living in 1950s Cuba, is struggling to pay for his teenage daughter's increasingly extravagant lifestyle. So when the British Secret Service asks him to become their äóÖman in Havana, he can't afford to say no. There's just one problem: he doesn't know anything! 

To avoid suspicion he begins to recruit non-existent sub-agents, concocting a series of intricate fictions. But Wormold soon discovers that his stories are closer to the truth than he could have ever imagine... 

In Clive Francis' adaptation, Graham Greene's classic satrical novel becomes a wonderfully funny and fast-moving romp.
