One of the party is funeral director Caradog LloydEvans Griffith, who briefly served in occupied Paris near the end of World War II. Caradog pays for his son Glyns air ticket on the proviso that Glyn Morris comes on a pilgrimage to find his little butterfly who he spent a short romantic period with during the war. This pilgrimage is successful and although the right place is found, it is no longer the innocent bistro of his youth but one of many strip club joints. Mr LloydEvans mistakes a young girl in the club who is a spitting image of his little butterfly for the real thing and finds that the girl is actually Odette Sharon Morgan, the daughter of his old flame. He is naturally disappointed but Glyn gets himself acquainted with Odette while Caradog reminisces with his butterfly played by Marika Rivera.A quick call to the hotel brings the entire tour party to the club where fun and frolicking takes place led by club secretary Mog Jones Davies, a retired player whose dreams of playing for his country were never realised. Some locals take exception and a mass brawl starts which ends with the arrival of the police. The whole party is arrested except Caradog protected by his butterfly Madame and Glyn hidden in Odettes bedroom. ........
