Ambitious Navy Intelligence officer Lt. Jordan O'Neil (Demi Moore) sets a historical precedent when she is chosen as the first female candidate for the Navy's elite Combined Reconnaissance Team training as a Navy SEAL. However, a disgruntled officer (Viggo Mortensen), who opposes integrating women into this prestigious corps, capitalises on the hostility felt for the new recruit by the men in his unit and rallies them against her, making every exercise an insurmountable task.
