La playa vacía (1977)

The holiday season ends and Victoria, a mature widow and owner of the motel by the beach, doesn't want to spend another winter alone. To avoid this, she buys Pablo's company to continue working for her. Pablo accepts, on the condition that he remains free and can enjoy other women. A few days later, Gloria, a beautiful biologist who claims to be preparing a book, arrives at the motel and, to Pablo's surprise, seems to know everything about Victoria and her past.
