Daniel has kept the keys to all the places he’s ever lived. Lena wants to use them – to go on the ultimate property porn tour of London, a wild weekend of getting to know each other intimately in other people’s homes. But what begins as a risky fantasy soon becomes a deadly threat. "7 Keys” is a cat and mouse thriller that never lets up, bringing the genre out of the 90s and into the now with a fresh female lens and wicked flashes of black humour. From tiny apartments to riverside penthouses, "7 Keys" is a wild ride through the hidden side of London, the dark underbelly of a modern city where young people struggle to find their place - and sometimes struggle to survive.
