A Slight Hangover is a funny and affectionate look at three generations of clever, witty and thoroughly immoral people. The notorious, 30-year ménage à trois of Lewis Messenger, Oscar Woodley, and Giselle Parmentier had ended with Giselle's death. Now the two old megastars, stuck irretrievably together in their Caribbean mansion, are forced to face up to their new living arrangements and nerves are beginning to fray. Then, an unexpected visitor: Giselle's long lost daughter, now middle-aged and towing her own, stunningly beautiful daughter Amanda behind her, arrives on their doorstep, demanding to know which one of them is her father. The trouble is, neither Oscar nor Lewis know--but it's enough that Amanda is the spitting image of Giselle.
