"There may be virtue on the road to salvation.

It all depends on who you go with..."

After Jamie and Matt are caught swindling money from their City of London firm, they set out on a chaotically comedic road trip, in an attempt to recoup their illicit earnings and pay off a gangland debt.

But faced with life or death from a Dublin gang boss, they are forced to follow the lead of an ex-IRA gangster and Jamie's ex-girlfriend. Along the way, they acquire a dead junkie, a Gen Z Emo, a Batman aficionado, and a chasing pack of zombie bikers, as they journey north in search of their only salvation: a loaded Scottish granny named Mavis Grind.

Will they reach Shetland in time to save their necks? Or will their journey go morally south and end in disaster?
