You can lookup the plot any where, i wont waste your time here so i will be quick. As the producers say, this show's ending was made with season 2's production in mind and since there is no season 2 or even any confirmation of it, this show lost its worth. Everything was going fine but the climax is super disturbing.

Spoiler *******
Theres a big mistake in the show, if only the lady before dying had told the M.C about the evidence most of the show wouldn't have happened nd i dont see any reason why she couldn't tell him since her life was in danger??? Lol.
This show doesnt deserve this 8.3 rating it currently has.
