Steve Zesso is a world-renowned marine explorer. He and his film crew often go to the world's oceans to shoot scientific and educational films exploring the underwater world. However, Zesso’s legendary life has caused huge waves, and his best friend and long-term partner, Eastban, was killed. The rumors spread quickly among the expedition. According to legend, the killer of Eastban was a jaguar shark that is hard to find in the world, and this marine monster may not exist at all. At this moment, a pilot named Ned Pritton claimed to be the son Steve had never met. Ned wanted to help the father and son reunite, so he asked to join Zesso's sailing expedition. Zesuo, who was a father for the first time, couldn't help but feel a trace of humiliation. Therefore, Zesso determined to take out the majesty and courage that the team leader and father should have, and set off on an expedition to find the mysterious jaguar shark. Steve Zesso re-assembled all the crew members and promised to make the mission into a documentary. This group of team members come from all over the world, including reporter Jean Winslet Richardson who is responsible for tracking Zeso’s documentary reports, Zeso’s long-distanced wife Irina Zeso, and co-producer Eli promise. The group of people set off on the "Belafinte" clipper, but waiting for them along the way was a series of overwhelming troubles such as pirates, kidnapping and bankruptcy.
