A plot bunny for you, take for a real life story

My God father is a catholic priest.
He organized a resistant group back in Pinochet's time that look out for Human Rights.
He has lots of amazing stories. The one I loved, was told by my granny some years ago, I've always felt it could be a good story to write:

After Pinochet raise power my uncle start working on
saving lives. Helping people from the resistance to get out of the country.
The most common thing was to jump an embassy wall and lived there. The real problem was
how to reach the airport or any frontiers without been catch?. (Remember Chilean
geography: North with the driest desert in the world, south with the Antartic,
orient the Andes, Occident with the Pacific Ocean)

In this context, a couple traspass the Vatican Embassy, she was in the latest months
of pregnancy. Once she give birth they manage to secretly send the couple
away...but not the baby, it was too risky.

So the baby stay at the embassy for a while, but it was impossible to take good care of her there. Two very fats nuns take it from there, inside
their robes, in a bishop car. (The army men don’t dare to register and touch the
ladies: they had their "morals".)

They went to have tea at my uncle's parish, and left the baby there, soon one of my aunties enter with her five kids and left, a few hours later, with
her six little ones. The family take care of the baby for a whole year, they
introduce her as the nanny's daughter.

One afternoon my uncle step in and take the baby to her parents.
My aunty never knew who the baby was.

A few years ago, in a TV show about dictatorship victims, a woman narrated her
story and tell she would love to thank the people who take care of her. My
aunt contact her the TV station and they meet.
