Prism is the daughter of the devil of the sea, Davy Jones. Wanting to create a sea that's free from her father's control, she steals his magic bottle. Whoever owns the bottle has the power to command all the water in the entire North Sea. By using the bottle's power, Prism is able to trap the sea's water inside of it, prohibiting Jones from entering the sea again. Her unauthorised usage of the bottle causes Prism's body to get cursed by turning into glass. She manages to escape to a small town, where she meets the cat Caesar. Together with the oyster catcher bird Bonnie, the three embark on a journey, to try and find a way to lift the glass curse off of Prism. Prism will face both allies as well as enemies who want the sea to return, forcing her to choose. On the one hand, Prism's body will always be at risk of shattering, should she be unable to lift the curse. But lifting the curse, would mean she would have to release the sea's water from the bottle again, allowing Davy Jones to return.
