On and around an offshore rig, a band of mercenaries lead by eco-terrorist Michael Kittredge (Vinnie Jones) move in with the intent of setting off an electromagnetic bomb that is intended to disable the entire US. More terrorist than environmentalist, Kittredge and his hired thugs abuse and terrorize the crew of the offshore rig. The noble “lawman” dispatched to deal with the baddies is FBI Agent Reed (Vivica Fox), but the real knight in shining armor is a tugboat captain, Lamont Dixon (Eddie Griffin), once a firefighter and now about the most unlikely choice imaginable for saving his country. Fortunately, the good guys recruit help in the form of Jamal (Breckin Meyer), a computer whiz on the rig who uses his computer skills to assist Dixon and Reed in tracking the plans and actions of the terrorists to help even the odds for Dixon and Reed in preventing the blast.
