In the shadow of the Range Rover murders, drugs, violence and revenge continue to reign in a criminal underworld even darker and deadlier than before as a new generation of Essex Boys begin to carve their bloody mark.
Four men, no strangers to unlawful transgressions, execute a daring football stadium robbery, but the volatile dynamic soon turns sour when the leader of the group becomes paranoid and begins to self destruct. Years later, after a stint in prison, the villainous leader is unrelenting in his path to retribution, he wants his years back and will take them from all of the men who know the true reasons for his prolonged captivity.
A British Police Officer, ground down from the job, comes home and relaxes by playing online with his best friend. Whilst talking via headset, he tells his friend about the terrible day he has had working on the County Lines project and how a child drug mule almost died in front of him. As he loses hope, his friend tells him how what he does matters in more ways than he can ever know, equating his good deeds to the Butterfly Effect, calling him a Butterfly on the Beat. The Officer cheers up and the two enjoy the rest of the night playing games together and talking online before he has to get up and do it all again.
