"The Unseen" is the story of Bob Langmore (Aden Young), who eight years earlier, abruptly left his wife Darlene (Camille Sullivan) and their daughter Eva (Julia Sarah Stone) behind, only to isolate himself in a small northern town. Bob made this sacrifice because he has a condition: he is becoming invisible. Not in the clean "Invisible Man" sort of way, but in an irregular, random and gradual complete loss of pigment in his skin. When Darlene reaches out to him, he returns to the city for one last chance to reconnect with his daughter, but when she goes missing, he will risk everything to find her, including exposing the secret that he is becoming invisible.
