Michael lives in two separate realities after a car accident. In one reality, his wife Hannah survives the accident; in the other reality, his son Rex survives. Michael does not know which reality is real, and uses the wristbands to differentiate the two. He sees two therapists Dr. Jonathan Lee in the red reality and Dr. Judith Evans in the green reality. At work, Michaels erratic behavior triggers clashes with his team; they do not know about Michaels uncanny ability to solve crimes using details from both realities.
