Adam Symes has a novel to finish and, with the proceeds, plans to marry Nina Blount. Returning from France, his manuscript is impounded as obscene by customs officers, while in the next room his friend Agatha Runcible is strip searched as a suspected jewel thief. She rings the newspapers about her fate. Adam rings Nina to say he cannot now marry her, and has to negotiate a penal new contract with his publisher.
Winning £1,000 on a bet, Adam gives it to a drunk major to place on a horse, but the major disappears. After a fancy dress party, where he meets up with Nina and Agatha, the young people go back to the home of a quiet girl who turns out to be the Prime Minister's daughter. Agatha, who is in Hawaiian costume, is kicked out, to the delight of press photographers. The implication of orgies at 10 Downing Street causes the collapse of the government.
Nina suggests that Adam asks her widowed father in the country for money to marry on. The eccentric old man comes up with a cheque for £1,000 and, in celebration, Adam takes Nina to a country hotel to claim her virginity. She claims not to have enjoyed it, and also points out to Adam that the signature on the cheque reads Charlie Chaplin.
The next big party in London is being held by Margot Metroland, whose private business is recruiting girls for Latin American brothels, and will feature an American lady evangelist with her choir of female angels. The party is crashed by Simon Balcairn, a friend of Adam's who is a gossip columnist, but Simon is kicked out and in despair gasses himself.
Simon's job is offered to Adam, who initially devotes much of his column to the exploits of his friends but finds he can only broaden the scope by invention. A dim childhood friend of Nina is transformed in dashing man-about-town Ginger Littlejohn. Still unable to marry, Nina suggests another attempt at her father. Adam finds the old man involved in the shooting of a historical film on his estate and comes away empty-handed.
While he was away, he got Nina and other friends to write his column, for which he is sacked. With friends, Adam goes to some motor races where he sees the drunk major, who says he has got Adam's winnings but then disappears. A drunk Agatha takes off in a racing car and crashes with serious injuries, from which she later dies.
Nina announces that she is engaged to Ginger, to which the jobless and penniless Adam reluctantly agrees if Ginger pays him £100. The nuptial pair fly off to France for their honeymoon, but Ginger is unable to join Nina for Christmas at the house of her father, who he has not yet met. Adam steps into the breach, sharing a bedroom as Nina's husband and watching her father's maladroit film.
War breaks out, in which Adam finds himself alone on a devastated battlefield in France. He comes across the drunk major, now a general, who still has his winnings and invites him to champagne in his staff car. There they find one of the evangelist's angels, back in Europe after her experiences in the South American entertainment industry. While general and angel flirt, an exhausted Adam falls asleep.
