Ep. 10: A Crowning Performance by the Gratan
The Nautilus pursues Gargoyle through the LeMar Straits until it runs into a dangerous trap. The submarine is surrounded on all sides by a field of mines, which can be triggered should the underwater current shifts or if the submarine dares to move. In a race against time, Grandis, Sanson, and Hanson propose to use their Gratan to take out three of the mines so that the Nautilus can safely escape from Gargoyle's trap. However, Sanson knocks Grandis out, fearing for her safety. He and Hanson set aboard the Gratan and begin their mission, but the tank begins to malfunction. Jean, who has sneaked aboard the tank, helps the pair as best as he can, but soon the Gratan's underwater camera shatters, leaving the Gratan blind. With Grandis communicating from the Nautilus bridge, the trio barely manages to succeed and save the submarine from a deadly fate. (Source: Wikipedia)
