The Signal(2014) -

Nic discovers that his legs, which previously required crutches due to a degenerative disease, have been replaced with advanced robotic prosthetics. The Ending & Twist

Nic is questioned by Dr. Wallace Damon (Laurence Fishburne), an enigmatic figure in a hazmat suit who claims the group was exposed to an "Extra-terrestrial Biological Entity" (EBE).

While traveling, the group attempts to track down a rival hacker known as Nomad , leading them to an abandoned house in the Nevada desert.

The film is widely discussed for its "mind-bending" finale. After escaping the facility, Nic realizes he is not on Earth. The facility is actually an immense alien spacecraft (numbered 2.3. 5.41) currently in space, docking at a home world. Furthermore, Dr. Damon is revealed to be a robotic alien, his name "Damon" being an anagram of the hacker "Nomad".

After a sudden, unsettling encounter at the house, Nic regains consciousness in a sterile, high-tech underground facility.
