D.C. industrialist Calvin Claymore and newspaper publisher Hal Thorne are at odds over a proposed European aid bill. Calvin's young daughter Laurie is romantically involved with Hal as well. At a nightclub owned by Whitney King, during a water ballet, Calvin meets performer Mary Morgan and, at King's suggestion, they begin to keep company. King turns up and demands the money, then kills Mary during a struggle over it.
