Guilt

In a residential street in Edinburgh, brothers Max and Jake run down an old man while Jake is driving them back from a wedding - stoned and uninsured. They carry on with their lives, hoping Walter's death will be passed off as natural causes, but the brothers end up being pulled further into Walter's world.

Season 2 begins as Max is released from prison after a two-year stint behind bars, and attempts to put his life back together. Unable to return to his old job, and with brother Jake now living in Chicago, Max realises he's going to have to work his way back up — which means working for his old accomplice, private detective and recovering alcoholic Kenny Burns.

Max and Jake find themselves back in Edinburgh , where they soon face a familiar danger.
