Output: Ohio highschooler Cassie Sullivan, armed with an M4 carbine, emerges from the woods to raid an abandoned gas station. Upon entering, she hears a male voice calling for help. She finds a wounded man, who points a gun at her, but they each put their weapons down. His other hand is under his jacket and as he takes it out, she sees a glint of metal and kills him. He was holding a Christian cross and the screen cuts to black to show her backstory. A citysized alien spaceship is circling Earth, containing extraterrestrials referred to as The Others. Ten days later, The Others unleash their 1st Wave, an electromagnetic pulse that permanently destroys all electrical power. The 2nd Wave has The Others manipulate the planets geology and fault lines, causing earthquakes and megatsunamis that destroy coastal cities and islands. For the 3rd Wave, The Others weaponize a strain of avian flu virus, with birds carrying the infectant across the planet. Cassies mother is one of the casualties. Cassie, her father and her younger brother Sam, find a refugee camp in the woods with roughly 300 survivors. A few days later, an army unit with working vehicles rolls into the camp. The units commander, Colonel Vosch, claims there is an imminent threat of a 4th Wave and they will take the children to safety at WrightPatterson Air Force Base, intending to bring the buses back to retrieve the adults. Cassie is separated from Sam, and witnesses the army massacring all the adults, her father included. Cassie scavenges her way toward the base, but is shot in the leg by an unseen shooter and passes out. About a week later, she wakes up in the farmhouse of a man named Evan Walker, who saved her. Cassie leaves towards the base with Evan, but learns that he is an Other, sent years ago as a sleeper agent and merged his consciousness into a human host. The sleepers roam their designated zones, killing human survivors. Evan admits his humanity was reactivated when he saw her, disagrees with the invasion and lets her leave. He warns that Colonel Vosch and the military are possessed by the consciousness of individual Others. At the base, the military have used deception and technology to convince the rescued children that the humans outside the base have been possessed. They provide military training to the children, forming them into squads to go on kill missions outside the base. Sam has been placed into a squad led by Ben, a boy Cassie had a crush on, along with Ringer, a tough teenage girl, Dumbo and Teacup. While out on a kill mission, Ringer removes her military implant, causing her to register as an Otherpossessed human on the squads scopes. The squad deduces the plan to have them kill real unpossessed humans, making them the 5th Wave. Ben sends his squad into the woods and returns to base, claiming his squad was killed, for the purpose of retrieving Sam, who was left behind. Ben confronts Colonel Vosch about child warriors being the 5th Wave and Cassie kills Sergeant Reznik during her oneonone indoctrination spiel. Ben and Cassie find each other and leave to find Sam. Evan sets off numerous bombs and advises them to quickly find Sam before the destruction of the entire facility. Colonel Vosch and the surviving military evacuate with the human children by military aircraft. Cassie, Ben and Sam escape, with help from Ringer, just as Evan completes the destruction of the base. Bens squad is reunited and Cassie ponders the strength of hope as humanitys driving force for survival.
