The whole village mourns when General O'Leary (A.E. Matthews), owner of a hunting estate in South Ireland, is killed in an accident. His nephew, Jasper O'Leary (David Niven), takes over the state and soon has aroused the displeasure of all, with the exception of Serena McGluskey (Yvonne De Carlo), as much a schemer as he is a cad. Led by Thady O'Heggarty (Barry Fitzgerald), the villagers plot to drive Jasper away. They use the occassion of "O'Leary Night", when the ghost of the first O'Leary walks the halls, to create general chaos. Written by Les Adams
