Plot Summary

In Invasion of the Mermaids (2025), the myth of the mermaid takes a terrifying turn in this oceanic horror epic that blends folklore with futuristic science. When a coastal research facility begins detecting strange seismic patterns and missing marine life, marine biologist Dr. Eliza Morgan (Sophie Cookson) is called in to investigate — but what she discovers is far from natural.

Uncovering a hidden underwater kingdom ruled by ancient, intelligent, and deadly mermaids, Eliza finds herself in the middle of an invasion plan centuries in the making. These aren’t the mermaids of fairy tales — they are apex predators, beautiful yet monstrous, capable of mimicking human voices and luring ships and submarines to their doom.

As the creatures emerge from the depths to claim coastal cities, Officer Finn Carter (Jacob Elordi) and Eliza must lead a desperate fight for survival, forming an uneasy alliance with Naya (Jessica Henwick), a rogue mermaid with a conscience. With the ocean rising and humanity on the brink, only ancient secrets and forbidden technology can stop the tide of destruction.
