A few days ago, in city of Miami, Florida, a storm has arrived and blew strong winds that made the weather really terrible and nearly caused a hurricane. During that storm, a strange creature has been washed up in a swimming pool. Then, a few people go missing whenever they try and clean out the pool. Some think of it as a shark, others think the Loch Ness Monster is eating these people up. But what people don't realize is that it's actually a man-eating mermaid, hunting her prey while trying to figure out a way to get out of the pool and back into the ocean. A few days later, college freshmen Hailey and Claire are hanging for the summer while in Miami. What they see is the horrible destruction caused by the storm and their favorite pool area they love to play in since they were kids. They decide to book a hotel to spend the night in so they can go and meet a friend. Meanwhile, the monster mermaid is still going on her rampage. Reports and eyewitnesses have said that her skin is the color of Aquamarine and she looks like " a zombie that come to life and starting to eat everyone. " Hearing the news about this, both Claire and Hailey warn their friends, including Raymond, the boy the girls have a crush on. But when Aquamarine spots her next prey, Raymond, Claire and Hailey must protect Raymond at all costs before Aquamarine catches up to him.
