The Night Shift (S02E03)

Wicky is called to a shooting in a technology shop, where he finds himself sharing the night shift with Kai, a shelf-stacking conspiracy theorist who is preparing for the end of the world – which he insists is just around the corner. Is he paranoid or just being sensible? Wicky isn’t sure, but either way, he has to decide where his own priorities lie. (BBC iPlayer)
