A film production company arrives at the park to make an under water monster movie. Flipper falls in love with the company's pretty star Ella Bailey and lingers at the filming site. When Flipper ruins some good shots, the director Monty Lucius resorts first to having a rifle fired at the dolphin and then a harpoon. Ellia is outraged and summons Porter. Things get out of hand before Porter arrives and the under water cameraman is wounded by the harpoon. Porter dives into the sea and brings the injured man to safety. The director apologizes to Porter.
