Second Sight follows DCI Ross Tanner (Clive Owen), a maverick cop who finds out that he has a rare disease which is causing him to go blind. Tanner's boss, Superintendent Lawson (Thomas Wheatley), little suspects that the man he named to head the elite Specialist Elite Murder Unit is losing his sight. Tanner struggles to keep his condition a secret, but soon asks himself how long can he keep solving crimes that not even the fully sighted can fathom. (wikipedia)
