After fighting off a gargantuan squid and cross examining their Company soldier stowaway, the crew of the Nautilus must take on food and water. The only non-company territory they can reach is Karajaan. There, the Rajah recognises Nemo as Prince Dakkar, and reveals to him the complicity Nemo's father had in his lands becoming controlled by the Company. When the Rajah betrays them, they must escape Karajaan before the Dreadnought arrives.
In the penal colony of Kalpani, captive Nemo and engineer Gustave Benoit secretly design a submarine, the Nautilus, with plans to escape. When Director Crawley arrives to seize the unfinished vessel for war, Nemo escapes with his crew. They're soon joined by Humility Lucas, a bright young engineer, and her maid Loti. On their epic voyage, Nemo battles enemies, explores a magnificent underwater world, and embraces his role as captain in an unforgettable adventure, determined to enact revenge against the ruthless East India Mercantile Company.
