Deepfaked to Death

LAPD detective Jon Eckhoff is jolted awake in the wee hours by a call from his union rep. A video is circulating on social media that supposedly shows Jon shooting a young man to death in a mostly-deserted warehouse. 

Jon has never shot anyone, in the line of duty or otherwise. To anyone who knows him, the video is clearly a deepfake. But who would do such a thing? Jon doesn't have any enemies.

Or does he?

Jon is suspended for the duration of the investigation. He can't do anything to help himself - but his friends at Angeles Investigations aren't content to wait for Internal Affairs to clear Jon. Rob, Kevin, Jamilah, Jamie, and Ryan all jump in to solve the mystery. Who's the victim? Where's the crime scene? Who would spend the considerable time and money to create the video?

And, most importantly, why?
