MacGyver - Season 2 Episode 15
Pirates

While on an expedition to find a Spanish treasure fleet, Dr. Barbara Ortegas boat is hi-jacked by modern-day pirates. They steal the small amount of treasure that she has already found - including the ships log, which is the key to finding the whole fleet - and take off. When she makes it public that she was hi-jacked, the Phoenix Foundation sends MacGyver to help. Now, MacGyver and Barbara must recover the ships log, so she can find the treasure before the pirates do.
