This is the story of Hannah's life. Or more specifically, why it ended.

The first teaser for Netflix's upcoming YA mystery series "13 Reasons Why" is here, debuted by pop star Selena Gomez on her Instagram (Gomez is a producer). The video also announces the premiere date, which is March 31.

The show is based on a bestselling YA novel, of course, like seemingly all Hollywood projects. High school teen Clay (Dylan Minnette) receives a box of recordings from his classmate Hannah (Katherine Langford), who committed suicide two weeks prior. The recordings name 13 people who helped drive Hannah to kill herself.

The teaser is certainly haunting, as we see glimpses of those people -- some looking regretful, others defiant. "Spotlight" director Tom McCarthy directed two episodes, and the cast boasts Kate Walsh, Derek Luke, and Brian d'Arcy James.
