Yet。Barking。and。Dagenham。police。failed。to。link。the。deaths,。until。weeks。after。the。fourth。one.。The。film。tells。the。story。through。eyes。of。the。families。of。Port's。victims,。unpicking。how。the。police。failed。to。properly。investigate。each。of。the。deaths。in。turn.。The。police's。assumptions。that。these。young。gay。men。had。died。from。self-inflicted。overdoses。of。chem-sex。drugs。allowed。Port。to。continue。raping。and。killing。innocent。young。men.
