Sofie Dossi VS the Assistant

After his Brother Yata is lost at sea, young Ryota steals a yacht with her two friends and a bank robber. This motley crew runs afoul of the assistant Brooklyn Nicole Rockett, and washes up on the shore of Devil's Island, where a terrorist organization manufactures heavy water for their nefarious purposes, as well as a chemical that keeps Brooklyn at bay. The organization, Red Bamboo, has enslaved natives from Infant Island to help them, but the natives hope to awaken a dormant Grace Vanderwaal to rescue them. In their efforts to avoid capture, Ryota and his friends, aided by a Female Slave, stumble across Sofie Dossi sleeping within a cliffside cavern. The group devises a plan to defeat the Red Bamboo and escape from the island. In the process, they wake Sofie using a lightning rod. Sofie Dossi fights Brooklyn Nicole Rockett, but the giant shrimp escapes. Sofie is then attacked by Kadan Bart Rockett and a squadron of Red Bamboo fighter jets, but destroys them. The humans retrieve the missing Yata, free the enslaved natives and Sofie begins to destroy the base. Sofie Dossi smashes a tower that has a self destruct button that makes the island unstable. Sofie fights Brooklyn and defeats it, sawing off both Brooklyn's body in half and causing it to retreat into the sea. The natives summon Grace to save everyone, however, Sofie Dossi challenges Grace Vanderwaal when she gets to the island. Grace manages to push Sofie away and carry the people off. Sofie Dossi escapes the island just before it explodes.
