On August 4, 2020, a fire in a Beirut port warehouse detonated roughly 2,750 tons of ammonium nitrate, flattening neighborhoods and killing over 200 people. This film reconstructs that day through survivor interviews, blast footage, and aftermath scenes of gutted apartment blocks and the port's crater, then works backward to explain how the chemical stockpile got there. It traces the cargo ship Rhosus, diverted to Beirut in 2013 with the explosive material aboard, and the seven years of neglect, bureaucratic buck-passing, and warnings ignored that left the stock sitting unsecured a few hundred meters from residential streets. Officials, engineers, and people who lost homes or family members describe both the physical shockwave and the political rot it exposed, as Lebanon's government faced accusations of corruption and criminal negligence in the explosion's wake. The film treats the blast as both a forensic mystery, how did this much explosive material go unregulated for so long, and a portrait of a city left to absorb the consequences.
