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

Max tries to derail the private detective he engaged to calm Walter's niece Angie's fears. Max is also dealing with threats from Walter's neighbor Sheila, who reveals that she witnessed something that night. For a price, she will keep her mouth shut. Can Max convince his increasingly suspicious wife, Claire, to part with the money under the guise of yet another lie?

Angie and Jake's burgeoning but complex relationship has hit a problem. Jake wants to make things work and starts asking questions about why Max controls the shop's accounting. Is there more to the record shop than it first appears? Unable to control his little brother's rocking of the boat, Max takes matters into his own hands, with terrifying results for Jake.

Sheila claims ignorance when she discovers Walter's real niece has been in contact. Max orders Jake to leave the country with Angie, promising to sort everything out. Angie is still suspicious of Max, and tries to prove to Jake that Max is not looking after his brother's best interests. Max and Angie have their own separate suspicions about Sheila's real involvement in the night of Walter's death.
