Under Siege (1992) is a high-octane action thriller directed by Andrew Davis, starring Steven Seagal as Casey Ryback, a former Navy SEAL who now works as a cook aboard the U.S.S. Missouri, a battleship stationed in the Pacific Ocean.

When a group of terrorists, led by a former CIA operative (played by Tommy Lee Jones), hijacks the ship and takes control, they threaten to launch the ship’s weapons system unless their demands are met.

Ryback, initially underestimated by the terrorists due to his lowly position, proves to be far more than just a cook as he begins to fight back and take down the invaders one by one.

The film is known for its intense action sequences, with Seagal’s character using his military training and resourcefulness to outsmart and overpower the terrorists. As Ryback works to thwart their plans and save the ship, the tension and suspense build, leading to thrilling confrontations.

Under Siege is widely regarded as one of Seagal’s most successful films, combining fast-paced action with a straightforward, engaging plot. It became a box office hit and cemented Seagal’s status as a leading action star in the 1990s.
