Mathew Horne narrates the dating series that tests what matters most when it comes to finding love - looks or personality? Each episode sees six singletons dating each other in the pitch black Dark Room. After getting up close and personal, will they be turned off when the lights are turned on? The participants will stay at a luxury mansion in the countryside, but with the girls and boys living on separate floors, they will only ever meet in total darkness. When the lights go on, the couples must ultimately decide whether to leave the mansion together or apart.
