Errol Flynn flies by helicopter from his Hollywood hills home to La Jolla to meet with his friends with the University of California's Scripps Institution of Oceanography. After some unplanned adventures and misadventures including following a pod of gray whales via helicopter, Flynn, on the request of the Institution's Dr.
Carl L. Hubbs, tells of the reason for his trip: to provide his schooner, the Zaca - including himself, his marine biologist father
Theodore Flynn, and the Zaca's crew - to do some important expedition work for the Institution, specifically to search for marine life that could be found on both the west and east coasts of the continent in order to study evolution as the once contiguous ocean was separated through plate tectonics over millions of years. As they travel south, through the Panama Canal, through the Caribbean and to the Atlantic, they encounter and collect a variety of small and large marine specimens. Despite the tireless work by all, they do manage to soak in some local culture along the way.
