A night out in Green Bay ends in a parent’s worst nightmare when Nicole Vanderheyden vanishes into the darkness after a heated argument at a local bar. When her body is discovered in a secluded field, local authorities immediately set their sights on the person closest to her: her boyfriend, Doug. With blood found in his garage and a history of domestic tension, the case seems closed before it even begins. However, a piece of wearable technology and a car’s GPS data provide a shocking alibi that turns the entire investigation upside down.
