PLOT: rags to riches

A  sibling makes every effort to find their long-lost brother/sister. Before they can track them down, they die, but in the will they've left the sibling a sizable amount of money/land/etc... A month or two later, the sibling is found (possibly homeless?) living destitute and is given the news of their brother/sisters death and fortune. This could go several ways... it could be a romance (maybe the person that tracked the person down helps get their act together & falls in love with them in the process) - a thriller (maybe the sibling was murdered & they somehow get involved due to the inheritance) - a drama (maybe they take the fortune they've inherited and open a huge homeless shelter for people like them)
