What happens when you buy your first family home, only to discover that you're living next to 'the neighbours from hell'?
Channel 4's new hour-long drama The People Next Door centres around Gemma and Richard, a young couple who have just moved into their first house together. It's a happy, exciting time for them, until they start hearing disturbing sounds through a wall and start suspecting something very sinister is going on next door.
