Screamboat (2025)

Aboard an old Staten Island Ferry named Mortimer, maintenance workers Neil and Dominique inadvertently release a mutant mouse, Steamboat Willie, from a sealed chamber below deck. The creature kills Neil before attacking Dominique.

Selena, a bartender with disillusioned dreams of becoming an artist, races to the ferry to escape a quintet of obnoxious socialites drunkenly celebrating a birthday. Selena has a meet-cute moment with Pete, a ferry employee who takes her aboard. While alone, Selena witnesses Willie murdering a police officer. Selena tries to alert Pete, an EMT named Amber, police officer Lieutenant Diaz, and first mate Tommy, yet no one believes her. After strangling Captain Bill Clark to death, Willie redirects the ferry's course. Throughout the rest of the night, Willie kills numerous passengers including Selena’s socialites from earlier, well as several cops and deckhands. Upon finding the captain's body, Tommy puts himself in charge and appoints Pete as the new first mate, directing Pete and Diaz to escort the passengers to the lower level for their safety. Amber also realises Selena was telling the truth when she sees Willie using a forklift to kill two other passengers.

Diaz rallies many of the surviving passengers against Willie, only to be suddenly killed by the latter with a pole through his throat. He then sprays the crowd with a firehose, before activating a power box to mass electrocute them. Matteo, the son of Borough President Molinari, is escorted by a burly man named Moses, and the two regroup with Selena, Amber, and Pete on the bridge. The five survivors encounter Barry, a former ferry deckhand who explains that Willie was once a normal rodent who was experimented on by mad scientists. The ferry’s benevolent captain, Walter, eventually discovered Willie and set him free, but the creature became deeply disturbed and disappeared following an unknown tragedy.

Pete and Selena share a kiss while searching with Amber, Moses, and Matteo to find distress signal flares. All of a sudden, Dominique appears and attacks Moses, revealing that since his initial attack, she has been doing Willie's bidding to help the mouse find another one of his kind in exchange for sparing her life. Despite this, Willie turns on and attacks Dominique following an encounter with Selena and Amber. Moses sacrifices himself by firing a flare whose resulting explosion kills Dominique. However, the blast also blows a hole in the ferry. With the ferry sinking, Selena and Amber save Matteo from drowning while Pete willingly stays behind to fight Willie, supposedly dying in the process. From a photograph recovered by Matteo, Selena and Amber discover Willie had a wife whose disappearance drove him to madness, and he redirected the ferry in an effort to search for her. Selena has Amber take Matteo to safety while she uses a trunk of theatre costumes to dress up as Willie's mate. Amber battles Willie until Selena arrives. Willie knocks Matteo into the ocean and pulls Selena back to safety. Amber distracts Willie, which allows Selena to stab him in his head with a pair of scissors, sending him falling into the ocean depths.

Matteo is pulled to safety by a rescue boat and reunites with his father, Molinari, who informs Selena and Amber that they are the only known survivors of Willie's killing spree aboard the ferry. Amber convinces Selena that the experience has hardened her as a New Yorker, so Selena decides to remain in the city to pursue her dream of becoming an artist. During the credits, Pete is seen radioing for help, implying that he is still alive.
