Lt. Jordan O'Neil (Demi Moore), a Navy topographic analyst who is chosen as a test case for the presence of women in combat. Aware that she is making history and knowing that 60% of all male trainees will fail the rigorous training, Lt. O'Neil struggles to prove herself physically and mentally worthy of becoming a Navy SEAL. What she doesn't know is that she is being sold out by hardbitten Texas senator Lillian DeHaven (Anne Bancroft), who is being blackmailed by the Defense Department with politically fatal base closings unless O'Neil fails the program. The central recruits are pushed to their physical limits by a grueling weeding-out process. Viggo Mortensen is outstanding as Master Chief John James Urgayle, a steely-eyed, tough-as-nails instructor who somehow finds time to quote D.H. Lawrence when he isn't making people eat garbage and beating O'Neil senseless as part of a training exercise.
