 A strange giant "sea monster" has been rampaging the seas.The American naval ship "Abraham Lincoln" is sent to investigate, but is rammed by the "monster" which turns out to be The "Nautilus", the fantastic submarine of the enigmatic Captain Nemo, and "Rudderless, the "Abraham Lincoln" drifts on".Then, in "A strange rescue" he guides the sub to surface under those pitched overboard and his crew take them, including Professor Pierre Aronnax and his daughter (both of whom are French) below through a hatch in the surface of the deck.
