Episode 1 – "The Calm" A local fishing captain vanishes along with his crew. The only clue: a damaged life raft bearing the logo of a defunct seafood plant. Lisa (Morven Christie) returns from leave, haunted by her brother’s death. The episode ends with an ominous weather alert: Hurricane Eira is now tracking directly toward the Bay.

BD50 Exclusive Extended Cut

Episode 4 – "The Deep" With floodwaters rising, Lisa dives into submerged archives (a visually stunning underwater sequence shot on 35mm, now scanned in 4K). She finds evidence of a mass cover-up — including her brother’s connection to the case. The episode ends on a cliffhanger: someone is waiting for her back at the station with a gun.

Episode 3 – "Storm Surge" The hurricane hits mid-investigation. Power cuts out. Lisa and her partner, DS Med Kharim (Taheen Modak), are trapped in the police station with the prime suspect — who claims he’s an innocent whistleblower. The BD50’s lossless Dolby Atmos track makes the storm feel terrifyingly real.

As a devastating storm barrels toward the Bay, Detective Sergeant Lisa Armstrong uncovers a conspiracy that connects a missing fishing trawler, a decades-old cold case, and a powerful local family willing to drown the truth forever. Synopsis (Blu-ray edition features):

Episode 2 – "Rising Swell" As residents board up windows, Lisa discovers the missing boat’s last known coordinates — near an underwater trench used decades ago for illegal dumping. A flashback (in 4K HDR on the BD50) reveals a 1999 cover-up involving the town’s mayor.
