Under Siege is a 1992 American action thriller film directed by Andrew Davis, written by J. F. Lawton, and starring Steven Seagal as a former Navy SEAL who must intercept a group of mercenaries, led by Tommy Lee Jones, after they commandeer the U.S. Navy battleship .


The battleship arrives at Pearl Harbor, where then-President George H. W. Bush announces that the ship will be decommissioned in California. Casey Ryback, a chief petty officer assigned as a culinary specialist, prepares meals in celebration of the birthday of commanding officer Captain Adams, against the orders of executive officer Commander Krill, who is having food and entertainment brought by helicopter. Krill provokes a tussle with Ryback. Unable to imprison Ryback in the brig without clearance from the captain, Krill detains Ryback in a freezer and places Marine Private Nash on guard. A helicopter lands on the ship's deck with a musical band and a group of caterers (who are in fact a band of mercenaries led by disillusioned former CIA operative William "Bill" Strannix), and also with ''Playboy'' Playmate Jordan Tate.
