Best friends Ruth and Megan run a vintage shop in Muswell Hill. When they stumble across a time machine, it occurs to them that stock is free if they 'borrow' it from the past. They don't want to change history or rob banks; they just want to find a nice Victorian lamp or authentic 80s bum bag without getting sucked into the hellish time-space vortex. The thing is, Time Travel Is Dangerous. Narrated by Grammy Award Nominee Stephen Fry.
