What will happen in 13 Reasons Why Season 4?

The official Netflix plot summary reads: "In the series' final season, Liberty High School's Senior Class prepares for graduation. But before they say goodbye, they'll have to keep a dangerous secret buried and face heartbreaking choices that might alter their lives forever."

Showrunner Brian Yorkey, meanwhile, hinted that 13 Reasons Why Season 4 will not have its own new mystery but will instead follow on from the events of the prior season. In those episodes, (spoiler alert) we saw the murder of Bryce pinned on Monty despite the late character having an alibi. Yorkey said to Entertainment Weekly: "Certainly we saw at the end of season 3 that Winston can alibi Monty and is upset at the way Monty was used by these kids to, in his mind, get away with murder, so Winston is certainly going to be a significant factor in season 4.

"Also, there are other people in Evergreen County, such as Sheriff Diaz, who will certainly become aware of the guns that get dredged up by the fishermen and that will make him curious and he will follow that trail. There are a number of other people who are wondering if the story that got told is really the true story, so they will be putting pressure on our kids and there will be the threat that the secret will come out."

This is something teased right from the start of the trailer for 13 Reasons Why Season 4, which begins with the cast discovering that someone has written "Monty was framed" on the door of the school.
