Podcast fan Anna thinks there's a time traveller working in her local post office. So, who else should she ask to investigate other than Rani Chandra? Unconvinced at first, Rani is shocked when an old friend warns her off. If UNIT don't want her looking into it, there must be something to the phenomena...But will Rani's quest for the truth drive a wedge between her and Luke?
