Captain Nemo is the second movie in the Nautilus trilogy. It features Max and Mara in their twenties sailing the Nautilus II to Lincoln island to save three hot air balloonists caught in a storm that crashed into the island. However, upon arrival, the engine of the Nautilus II is damaged by a pirate attack, and they must wait seven days for Captain "Neb" to repair it. In the meantime, they find extraordinary secrets about the life of Captain Nemo, including the astounding fact that he is still alive, and that he has built a machine that could determine the fate of maritime power forever. The movie features the struggles of the six castaways as they try to unravel the mystery of Nemo and prevent the pirates from getting the machine. The film, though not as successful as Nautilus, was still a major box office success.
