Flipper

Dr. Keith Ricks (Brian Wimmer) returns to Bal Harbor in the Florida Keys to lead a dolphin research team. Dr. Pam Blondel (Colleen Flynn), a naval officer, joins the team, but her son (Payton Haas) isn't happy about his new living situation.

A band of pirates attacks the yacht of Andre Slater, a wealthy lawyer. The pirates destroy it with an explosion. Keith grows suspicious when a salvage boat arrives in the wake of the blast and later learns the yacht was carrying mysterious cargo.

After blowing up a shrimp trawler, a psychotic environmental activist also known as the "Green Freak" sets his sights on the Institute and plants a bomb in one of its computers. At the Institute, Keith and Pam decide to go to a seminar on bat sonar.

Keith and his friend Alan, a tuna fisherman, spend the day diving. A doctored videotape is broadcast showing Alan brutalizing a dolphin caught in his net. Keith later discovers that his friend was unjustly framed by his wife and her scheming lover.

A shady hotel owner offers Keith $10,000 to buy one of the Institute's dolphins to star in the aquatic show at his new Cuban resort. When Keith refuses, Flipper is kidnapped. Keith attempts to sneak into Cuba to rescue Flipper but is soon captured.

When Flipper helps Keith, Pam and Alex discover an illegal shark-finning line, the team find several sharks hooked, bleeding and finless. They immediately file a report with the marine patrol, which sends older brother Sandy to investigate.
