A man left on a stranger's doorstep finds a painful family secret, and a woman discovered in the back of an Aston Martin car in the 1950s learns why she was put there.

Paul is a police detective who was discovered on the steps of a North London church in 1964. He has very limited info about his circumstances; he doesn't even know the name of the church in question, though the team are able to track down some more concrete info about his birth. Caroline Harris-Gray was abandoned at the Prince of Wales Hospital in 1968, but wasn't aware of any coverage of her discovery. Luckily, the search team are able to find a connection back to her family in an online database, allowing her to reconnect with surviving members of her family.
