There is most definitely something in the water. What it is, though, remains mysterious in Below.
After the brief teaser last month, now Netflix has premiered the full-length trailer for the upcoming six-episode series.
Below stars Josh Hartnett as fisherman Calvin Penney, a big‑hearted but stubborn man haunted by the mysterious death of his father decades earlier.

When an unidentified sea creature begins terrorising his small Newfoundland hometown, and he must fight to hold his close-knit community together.
As things spin out of control, he fights to keep his son Wade (Charlie Heaton) and the rest of his family safe, while teaming up with a visiting marine researcher (Mackenzie Davis) as they uncover some deep secrets about the island.
Willow Kean, Ruby Stokes and Kaleb Horn co-star.
Netflix have been clear that this is not a supernatural story. Jesse McKeown is the creator, showrunner and executive producer alongside Harnett, Jessica Rhoades, Chris Hatcher, Jamie Childs, Louise Sutton, and Sharon Hall.
Below is released on Netflix on October 8th.
