Kattis Ahlström and Niklas Källner search for people who have a right to an inheritance and uncover unkown family stories.

Finding an Heir (Arvinge okänd) focus on people who have died in Sweden, seemingly alone, and without the authorities succeeding to find possible family members. The hosts take on the task to find the unknown heirs, and the program then succeeds to reunite families, heal wounds and tell stories about our modern history.
