The story is that Katalin's sister was deathly ill with typhus, so she buried her in the ground on a remote part of the camp grounds with a small pipe sticking up to the surface for her to breathe. The sister stayed like this for 30 days, with Katalin sneaking food and water to her, and a Jewish camp doctor snuck medicine.
I don't know what to tell you if you believe this steaming pile of horse sh*t.
