A boy named Clay receives a shoe box of cassette tapes from his late classmate and crush Hannah, after she recently committed sleeping. On the tapes, which are mailed with instructions to pass along from one student to another, Hannah explains to 12 peers how they each played a role in her passing, by giving 13 reasons explaining why she took her life.
**NOTE: Even though Netflix releases all episodes of 13 Reasons Why on one day, they are portrayed on the TV Calendar as airing one episode a day, for ease of visualisation.
