On July 12th, 2018, a deliveryman with no criminal past stabs a developer to death in Philadelphia's toniest neighborhood. What really happened that night?

Philly's D.A. lowers charges in the case: what happened that night was not murder, he says. But the victim's family is outraged.

The case goes to trial with evidence that should be determinative: cell phone video of the stabbing. But what does the video really show? Is this justice?
