Under Siege is a 1992 action film, in which a band of terrorists captures a warship with nuclear weapons, and threaten the world with armageddon. The only thing in their way is a ship's cook (Segal), who just happens to be a retiring former Navy SEAL with special-weapons, aikido and hand-to-hand combat training.

Under Siege was rated R by the MPAA. It stars Steven Seagal, Tommy Lee Jones, Gary Busey, Patrick O'Neal and Erika Eleniak and was directed by Andrew Davis.
