Black comedy about the relationship between a dissatisfied London Underground driver and an estranged father. When two people are run over by Paul's (Mackenzie Crook) tube train in a matter of days, his colleagues let him in on a little-known rule. If, in the space of a month, three fatal accidents occur while you're driving, then you're paid off with ten years' salary in a lump sum. Looking to clear his debts and find time to write a novel, Paul sets out to find a willing accomplice. After a few understandable knockbacks he meets Tommy (Colm Meaney), about to end it all by jumping from Holborn Viaduct. To Paul's amazement, Tommy agrees to be a literal fall guy. The two travel north for the weekend so that Tommy can attempt to reconcile things with his long-abandoned family before taking the fatal plunge. As the weekend progresses, the unlikely duo find themselves becoming friends. But a deal's a deal, so what will happen when Monday rolls around?
