The assassination of a beloved Palestinian-American activist in Southern California ignites a 40-year quest for justice, revealing the roots of a dangerous political movement that thrives today.

Why has the murder of Alex Odeh gone unsolved for over 40 years when the suspects have been known all along?

This is the motivating question of this investigative documentary with a political twist. The inquiry into who literally planted the bomb that killed Alex Odeh unfolds into a more complex set of questions at the heart of US-Israel relations.

A saved voicemail, a confrontational interview cut short, an FBI memo, a confidential informant... all are fragments or puzzle pieces, begging to be assembled, to answer not just who did it, but why the murder of Alex Odeh has gone unsolved for four decades.
