Siren (Seasons 1–3)

Siren (2018) is a sci-fi fantasy series from Freeform you can watch online on iFILM. The fishing town of Bristol Cove has always had a mermaid legend. Then a girl named Ryn walks out of the ocean — and the legend turns out to be something far more dangerous.

Marine biologist Ben Pownall and his partner Maddie try to figure out what Ryn is and why she came ashore. Eline Powell, Alex Roe, and Fola Evans-Akingbola carry the story across three seasons — 36 episodes about what happens when deep-sea predators decide to take back what's theirs. Generations of fishing-town secrets surface alongside them, and Bristol Cove is never quiet again.
