Sea Fever (2020)

A small crew aboard a fishing trawler heads out into the open sea, expecting a routine trip with the usual risks of the job. When their boat suddenly stalls after running into something strange in the water, they realize they're not dealing with a normal mechanical problem. An unknown organism latches onto the hull, and soon crew members start showing alarming symptoms-both physical and psychological. With communication cut off and no way to call for help, suspicion and paranoia spread as everyone tries to figure out who might be infected and what exactly they're up against. The story sticks tight to the claustrophobic setting, building tension as the crew struggles with both the monster outside and the breakdown of trust inside. As things spiral, they're forced to decide how far they'll go to contain the threat and make it out alive, knowing any wrong move could doom them all.
