Imagine trying to decide what to do if, from nowhere, you inherited a property you didn’t know existed? In this brand-new series Jean Johansson follows the hunt to track and trace the rightful inheritors to properties who have been left by a distant relative who didn’t leave a will – and surprise them with their unexpected windfall. 

With millions of properties waiting to be reclaimed, we follow inheritors as they see their new property for the first time, discover how much their inheritance is worth and reunite with family members they’ve never met.

And after taking advice from a property expert, together they must decide, do they keep it in the family or sell their Key to a Fortune?
