It's Baltimore, 1999. Hae Min Lee, a popular high-school senior, disappeared sometime after school and before work one day. Six weeks after she disappeared, detectives arrested her classmate and ex-boyfriend, Adnan Syed, for her murder. Syed claimed his innocence, but damning testimony from a close friend quickly put him at the top of the suspects list. A classmate at Woodlawn High School claims she knows that Adnan's whereabouts prove he couldn't have committed the crime, but others still claim he is responsible. Who is telling truth and who has the answers to Hae Min's untimely death? The case remains solved, yet unanswered questions cast doubt on the outcome of the investigation.
