Lenny is alerted to the recent arrival of a notorious Albanian gangster Tarek Sokoli. Sokoli wants to put down roots in his new homeland and that includes running drugs and prostitution rackets. Rather than have him killed, Lenny instructs Mercer, Rose and Calum to scare him away - to send the message to any others planning on setting up in London that their attempts will fail. He wants them to work as a team. Calum frees the prostitutes that Sokoli’s crew had illegally shipped in by returning their passports. However, after one of the liberated girls is killed, and a heroin importer is murdered by Sokoli’s lieutenant after Mercer convinced him against doing business with the Albanians, the unit begin to realise that simply executing Sokoli would have created far less bloodshed.
