A night bus might seem an odd vehicle to be driving through the centre of a thriller. Its driver, Francesco, is a down at heel bachelor who spends his long days gambling and hiding from a thuggish debt-collector known as the Bear. It is only when he pairs up with Leila, a sharp-witted and beautiful prostitute who makes her living drugging and robbing her clients--before or after bed, whichever is easier-- that his life takes on something like a sheen of glamour.
