Clay Jensen finds a box filled with audio cassette tapes anonymously left on his front doorstep. He plays the first in his father's boombox and realizes they have been recorded by his recently deceased classmate Hannah Baker before he accidentally drops and breaks the boombox when surprised by his mother. Clay steals his friend Tony's Walkman to continue listening. Clay listens to the first tape, in which Hannah begins to relate the experiences that led to her suicide. She starts by sharing the story of her first kiss, with Justin Foley, who goes on to inadvertently spread a salacious rumor that begins the sequence of events leading to her suicide. Clay is revealed, through numerous short flashbacks, to have been in love with Hannah and to have worked with her at the local movie theater. It is revealed in this episode that Hannah has put her friend Tony in charge of the tapes.
