Literally nothing happens, but in the last 10ish minutes. Typical conversation in this movie: "It's me, I am the sister of your aunt, and I was born before she was born. Your grandfather is my and your sister's father, and you are his grandson. And we are his daughters. Your grandmother, who is my mother and my sister's mother, who is your grandmother and also the wife of your grandfather, who is my father, and my sister and your aunt's father."
