Roberta Findlay – Honeysuckle Rose (1981)
Kate and Sam are a loving couple who want desperately to get rich, but when Kate blows their savings by buying a race horse named Honeysuckle Rose who never wins, it puts a mean strain on their marriage. They begin to fight and eventually seek solace in the arms of others in a series of torrid extra-marital affairs. Later, Honeysuckle Rose unexpectedly starts to win and their fortunes change. Now they’re rolling in dough and can debauch together as a couple. Samantha Strong and John Holmes star as the wayward couple, and the legendary Mr. Holmes is, as always, a spectacle to watch while in action, if not while acting.
