故事并不复杂：故事发生在1866年，法国人阿龙纳斯，一位生物学家，应邀赴美参加一项科学考察活动。这时，海上出了个怪物，在全世界闹得沸沸扬扬。科考活动结束之后，生物学家正准备束装就道，返回法国，却接到美国海军部的邀请，于是改弦更张，登上了一艘驱逐舰，参与“把那个怪物从海洋中清除出去 ”的活动。
经过千辛万苦，“怪物”未被清除，驱逐舰反被“怪物”重撞，生物学家和他的仆人以及为清除“怪物”被特意请到驱逐舰上来的一名捕鲸手，都成了“怪物”的俘虏!结果发现“怪物”是一艘尚不为世人所知的潜水艇，名“鹦鹉螺”号。
潜艇对俘虏倒也优待；只是，为了保守自己的秘密，潜艇艇长尼摩从此永远不许他们离开。阿龙纳斯一行别无选择，只能跟着潜水艇周游各大洋。十个月之后，这三个人终于在极其险恶的情况下逃脱，生物学家才得以把这件海底秘密公诸于世。
Story started at 1866, Aronnax was French, he is a natural historian, and he was studying a large monster under the sea. At that time, this large monster’s massager was traveling around the world. And after the investigation, he would return from abroad, and then he received an invitation from sea forces of the America. So he climbed up the chaser of America, to make the large monster die out.
By the hardship, the large monster wasn’t being dying, but Aronnax and his servant, a whaler came the captive of the large monster——nobody know it——a submarine called “Nautilus”.
They stayed there not bad, but captain Nemo doesn’t let them leave, they need to keep secret. And ten months later, they run away, and tell everyone the truth.
