The show was initially inspired by the novel of the same name by Jay Asher and focused on the suicide of Hannah Baker (Katherine Langford), who created tapes detailling the 13 reasons why she killed herself.

Series three ended with the shocking death of Monty (Timothy Granaderos), who was in prison following his sexual assault of Tyler (Devin Druid).

So far it is not known how Monty died, but he was used as a scapegoat to take the blame for the death of Bryce (Justin Prentice), but the truth of his innocence may not stay hidden.
