The Signal (2014)

Three MIT students - Jonah, Nic and Haley - are on a road trip to take Haley to California, a decision that's stressing Nic & Haley's relationship. Haley feels Nic is distancing himself from her and Nic explains he doesn't want his muscular dystrophy to hold her back. During their stay in a hotel, Nic and Jonah discover that the hacker NOMAD (who nearly got Jonah and Nic expelled for breaking into MIT servers), has found their location and is taunting them with strange and ominous emails. They track NOMAD to an abandoned house in the middle of Nevada near their path and decide to go after him. After finding nothing in the house, Nic and Jonah black out as Haley is pulled into the air by an unseen force.

Nic, now with 2.3.5.41 tattooed on his arm, wakes up in a strange and sterile underground research facility, where he is questioned by Dr. Wallace Damon, the head of the "transition group" in helping with his strange situation. He tells Nic what they encountered near the house was an EBE: an extra-terrestrial biological entity. Nic remains in disbelief. He is taken to his room where he hears Jonah talking to him through a small vent in the wall, saying his "body feels weird." Nic also notices that his legs, which were previously weak but functional, were now completely numb. When Dr. Damon questions Nic again, Nic tries to get answers about Haley's condition (who is in a coma at the time), but to no avail. After another night, a security alarm goes off and Jonah disappears. Nic and other personnel in the facility find large scorch marks running across the walls. Nic asks Damon where Jonah went, but Damon says Jonah was "never recovered" from the house. Nic tries to break Haley out, but is stopped. After they restrain Nic, he's shocked to discover that his legs have been amputated and replaced by prosthetic legs, made from alien technology. Using these new limbs, Nic breaks himself and Haley out, only to discover they're in the middle of nowhere.

After hijacking a semi-truck, Nic and Haley try to find a way around a seemingly endless canyon that extends around the facility and surrounding area. At a visitor's center, they soon come across Jonah disguised as one of the facility's men dressed in a white HAZMAT. Jonah reveals that he too had limbs taken from him, as his forearms have been replaced with the same alien technology. Jonah speculates that they're all in Area 51 and that this is all a test. After Nic discovers alien tech also implanted on Haley's spine, the trio drive up to a military checkpoint where Jonah tries to hack into their systems only to be shot at, eventually fatally. Nic and Jonah hug as Jonah prepares for his final stand to enable Nic and Haley's escape. He uses his remaining strength and alien tech to subdue the group of soldiers. However, Nic and Haley's escape is short-lived; as they approach the only bridge that would take them over the canyon to the outside world, they soon run into Damon and his military men who blow out the truck's tires. Haley is evacuated by chopper beyond the canyon and, knowing that Nic has mastered use of his legs, Damon tells Nic "you can't reach her." After hearing a loud horn coming from the sky, Nic realizes Damon is NOMAD. Damon then explains that it was Nic who came looking for him, that this was his fault, and adding that Nic is "the perfect integration of human will and alien technology. Our finest achievement." Agitated and emotionally compromised, Nic's bionic legs enable him to sprint at sonic speed across the bridge in the direction of Haley's chopper where he hits an invisible barrier and breaks through.

Nic finds himself inside what appears to be a different facility that is behind the image of the outside world beyond the canyon. Turning back toward the bridge, he sees Damon remove his helmet to reveal he's actually a robotic alien AI. Nic walks towards a window and realizes he isn't in a facility, but is on an alien ship numbered 2.3.5.41 that is about to dock at their home-world (signaled by the horn).
