The movie opens with Atlantis under attack from another underwater kingdom. During the war River Aeneas is called to help in the fight but while invading the other kingdom runs into the princess of the other kingdom named Nehalennia who tells him she doesn't want war and her father Aquarius is forcing his army to fight in the war. River tells her they can escape together because he doesn't want war either. After getting back to Triton's castle River tells Triton that the princess doesn't want war and they should try to reason with the others. Triton gets furious that River has made friends with the enemy and banishes them. They try to go to the other kingdom, but King Aquarius banishes Nehalennia. The two of them end up having to live on land for a while and end up meeting a man named Jake Finnigan who after Hermes 3 escaped the Confined after regaining his powers. Jake recognizes River as the man who worked with Hermes and so he attacks them. The movie ends with them beating Jake and Jake running away and with them not being able to go back to their kingdoms they create a name for Nehalennia so she can act as a citizen of New York and so they name her Lauren Aeneas, and she acts like she's River's brother.
