Taylor, a prison cook who has been incarcerated for 13 years, is informed he is eligible for early release on the basis he maintains good behaviour. Taylor regularly does haircuts for fellow prisoners Gaz and Paul, from whom he buys drugs to fuel his addiction. He also tries to get in contact with his now 14-year-old son Adam.

While struggling to fill out the form for his release, Taylor is assigned a new cellmate, Dee, who starts selling drugs not long after his arrival, taking business away from Gaz and Paul. Taylor and Dee start to form a friendship, with Taylor opening up about how he accidentally killed a teenager by selling him drugs to provide for Adam, which landed him in prison with a manslaughter charge. Dee lets Taylor use his phone to contact Adam, also sending Adam a pair of shoes via his friend on the outside as a present from Taylor. Frustrated with how Dee has taken away their control over the prison's drug trade, Gaz and Paul violently attack and beat him unconscious while Taylor stands back helpless. Afterwards, the pair force Taylor to punch Dee, filming it to share around the prison. Dee is taken to the hospital to recover.

Upon Dee’s return, he attacks Taylor for not backing him up. Taylor is forced to become a mule for Dee, collecting drug drops from the courtyard. While running a drop over to Dee, Taylor is stopped by Gaz and his associates. Their attempts to get Taylor to give them the drugs are stopped when Dee attacks them all, inciting a riot among the prisoners. Tensions further escalate when Gaz and Paul post a video inciting other prisoners to kill Dee in exchange for money. At the same time, Taylor starts to go cold turkey on the drugs.

After forcing Taylor to steal a knife from the kitchen, Dee blackmails Taylor into going to kill Gaz and Paul with it, claiming that Dee will get his friends on the outside to kill Adam if Taylor does not go through with it. A day before Taylor is set to be released, he cooks Dee a meal before leaving to kill Gaz and Paul mid-haircut. Taylor, however, does not go through with it, returning to his cell to find Dee having overdosed on the drugs he had spiked his food with. Dee realises what has happened, and after a brief fight, he slumps over, exhausted. Taylor shares his joint with Dee before Dee dies. The next morning Taylor sets Dee up in his bed to make it look as if Dee overdosed in the night. Later that day, Taylor is released, and a prisoner films him leaving the grounds.
