Journalist's Harrowing Ordeal on Luxury Yacht Cruise

In October 2025, investigative journalist Lo Blacklock is assigned to cover the maiden voyage of the luxurious yacht Aurora Borealis, owned by shipping magnate Richard Bullmer. The purpose of the trip is a high-society fundraiser for a cancer foundation dedicated to Bullmer's ailing wife.

Lo, who is still recovering from a previous traumatic incident, wakes one night to witness a body being thrown overboard from the adjacent Cabin 10. However, when she raises the alarm, every passenger on board is accounted for, and Cabin 10 is listed as empty.

As Lo's paranoia increases, she is forced to navigate the dismissive skepticism of the ship's elite. While the initial setup promises classic misdirection, the plot twist is revealed too soon, dulling the tension and allowing the audience to predict the foregone conclusion.

Despite Keira Knightley's convincing performance as the spiraling journalist, the film's flaws prevent it from being more than a mildly engaging psychological thriller. The familiar tropes and predictable course keep it well below the high-tide mark.
