O tempo olha para a vida no sistema penal britânico através dos olhos de dois homens muito diferentes. Mark foi separado de sua família. Aqueles sob os cuidados de Eric são protegidos. Um dos presos mais perigosos tem uma fraqueza..

Através de uma série de chamadas telefónicas interligadas, esta inovadora série conta a misteriosa história de um grupo de estranhos cujas vidas se agitam no prenúncio de um evento apocalíptico.

It's an iconic line in any crime story: when a suspect is arrested and gets to make one call. In reality, once a person enters the criminal justice system, there are multiple opportunities to make calls while awaiting trial. The vast majority of those calls are recorded. An admission, a threat, a slip of the tongue, a bribe -- it's all on tape and the suspect knows it, but this doesn't always prevent people from talking and talking. Jailhouse phone calls are used to frame the narrative of murder investigations steeped in mystery.

Hit hard by the Lehman shock, a well-meaning young man joins a phone scam operation and gets increasingly embroiled in the underworld.
