Captain Jung Tae-yoon (Rain), a South Korean Air Force pilot in the Black Eagles aerobatic team, performs a cocky and dangerous maneuver during an air show and is transferred to the 21st Fighter Wing, a combat unit flying the F-15K strike fighter. There he meets Cheol-hee (Yoo Jun-sang), the unit's own top gun. The two come into conflict immediately, since Tae-hun is free-spirited, whereas Cheol-hee plays by the rules. However, when a reconnaissance mission unexpectedly becomes an incident, the two team up to rescue their missing comrades and avert a nuclear exchange between North and South Korea. As a consequence of the mission, an F-15 has been shot down on the North Korean side of the Demilitarized Zone and a Korean People's Air Force MiG-29 entered South Korean airspace and bombed Seoul.

A rescue mission is sent, with South Korean air force pararescue in heavily armed Blackhawk helicopters supported by a strike package involving a KAI T-50 and F-15s armed with Mavericks, JDAMS and Sidewinders. The F-15 pilots manage to down the rogue MiG-29 which earlier attacked Seoul and restore the honour of their country and their squadron by shooting it down using an AIM-9 sidewinder air-to-air missile. During the dogfight, the MiG stalls, giving the pilot of the F-15K an opportunity to shoot it down. The rescue mission and a strike against a nuclear silo are a success, however, the T-50 is lost while trying to evade a SAM. Despite the odds, the pilot survives; the end shows Jung giving his final respects to his fallen comrade.
