In 2013, while working a case at the NYPD, Samuel Reid found a mysterious watch at a crime, which he stole for himself, believing it was connected to his father's 2000 murder.
Upon discovering the watch had time-travelling powers, he opened a private investigation firm alongside his good friend, defence attorney Zahra Modi. Now he uses the watch to travel back in time and solve cases.
There's just one catch: He can't interfere, lest space and time collapse due to resulting butterfly effects.
