Limetown, a chilling new podcast, is your paranormal Serial replacement.

Limetown follows an American Public Radio investigation into the disappearance of an entire Tennessee research facility. More than 300 people vanished from Limetown without a trace, leaving nothing so minimal as even “spit somewhere on a toothbrush” behind. Limetown was supposed to be a utopia in which neuroscientists could gather to research some mysterious greater cause, which was never shared with the public.

Instead, Limetown became just another experiment gone horribly awry.
