The BBC knows how to make shows that keep you on the edge of your seat and its latest offering, Nightsleeper, might just be one of its most nerve-jangling dramas in years.
Nightsleeper is now available in full to watch in the UK on the free BBC iPlayer streaming service. But don't worry if you're on holiday while it's on, because you can watch Nightsleeper on iPlayer from anywhere with a VPN .
