Inspired by the actual CIA mind-control experimentation project, MK-Ultra, 'Signals 2' is the second installment of the sci-fi feature tetralogy series, 'Signals.' The storyline continues to follow Nick Marconi, an American soldier victimized by his government's experiments upon him. Tortured by the life and death decisions he must make everyday as he meets people in need of his healing powers, he trudges on, unable to age or die, in search of a son he never knew, and yet the boy also possesses the same powers as Nick. He has also lost the power to telepathically connect with his soul mate as he used to, making his 'life-sentence' on Earth all the more unbearable.
