When 19-year-old aspiring artist Sarah Stern goes missing just weeks before Christmas 2016, investigators initially suspect she may have died by suicide or run away from home. Then, in January 2017, one of Sarah's former high school classmates comes forward with chilling information that leads to an undercover police sting and the shocking arrests of two very familiar faces. Armed with a bombshell, caught-on-tape confession from one of the suspects and the damning testimony of the other, Monmouth County, New Jersey prosecutors face the uphill task of trying to secure a murder conviction without a body for only the second time in the state's history. Features interviews include Sarah's father, detectives and prosecutors, along with complete access to archival materials detailing the search and the undercover sting operation.
