In February 1942, U.S. armed forces engaged unidentified flying objects above Los Angeles . Now, almost 70 years later, the alien invaders have returned.

In the opening scene, a large alien spaceship arrives hovering over Los Angeles. A fighter strike squadron is scrambled up and destroyed by the alien ship. Missiles fired by the aircraft at the alien ship go astray due to the ship transmitting countermeasure signals which instead hit the aircraft. One survivor, a female pilot named Solano, successfully bails out from her plane.

Next, smaller alien craft attack a U.S. military base near Los Angeles. Lt. Tyler Laughlin, a U.S. Marine, leads a group of survivors through the chaos to find a safe haven. During the trek across the wasteland which was once Los Angeles, Laughlin and his group find a World War II era pilot named Lt. Peter Rogers who claims that he and his fighter squadron were abducted by aliens back in 1942 over the Atlantic Ocean in the so-called Bermuda Triangle. Rogers is welcomed into Laughlin's group as is Solano who meets up with them. Soon, the group of Marines encounter a sword-wielding special forces agent named Karla who takes them to a top-secret underground bunker where she reveals to them that a secret branch of the U.S. government had kept an alien captive in a lab for the past 60 years when his spaceship crashed. Just then, Rogers reveals himself to be an android clone who kills most of the base faculty and reveals the alien's plans for the colonization of Earth and extermination of humans.

After destroying Rogers, three human survivors, Laughlin, Karla, and Solano, escape and commandeer the alien's spacecraft where they fly into the alien mother ship still over the city to take it down to stop the alien invasion. On the alien mother ship, the three humans encounter a large dragon-like alien guarding the ship's engines in which Solano is killed, but Karla and Laughlin succeed in killing it and setting explosive charges which leads to them escaping just in time as the alien ship explodes and crashes. Karla and Laughlin succeed in crash landing to view the devastation of Los Angeles, but relieved that the rest of Earth is saved.
