Serial episode one starts off by giving us the background information of a real life case that took place in 1999. The first episode gives us a broad summary of everything that took place leading up to Adnan Syed's conviction. Adnan Syed was a high schooler who was found guilty of murdering his ex-girlfriend Hae Lee. Sarah Koenig narrates the podcast. Although she's not a detective or a private investigator, she is trying to find an alibi for Adnan Syed to get him out of prison. The episodes start off very general and then goes into depth about all the people that were involved. The podcast raises a lot of questions as most of the evidence presented in Syed's trial were circumstantial.
The main piece of evidence against Adnan is a testimony by Jay who blames Adnan for Hae Lee's murder. That is the backbone of the state's case against Adnan. There was no physical proof that he did it. However, what doesn't help is the fact that Adnan does not have any alibi because he does not recall exactly what what he did on that day. More importantly, he does not remember what he did during the 21 minutes that Hae was murdered.
