Keep your family close, because your enemies are closer.

NYU student Matt Pine gets devastating news. Nearly his entire family have been found dead while vacationing in Mexico. The local police claim it was an accident, but the FBI aren't convinced – and they won't tell Matt why.

The tragedy thrusts his family into the media spotlight again. Matt's older brother, Danny – serving a life sentence for murdering his teenage girlfriend Charlotte – was the subject of a viral true-crime documentary claiming Danny was wrongfully convicted. Yet Matt's never been certain of his brother's innocence.

Now his family's murder is overlapping with Danny's case, Matt is determined to uncover the truth behind the crime that sent his brother to prison – putting his own life in peril and forcing him to confront his every last fear.
