Anna Andersson Timeline and Summary

Anna tells her brother to be brave after their dad dies, then she and her stepmom, Nadya, run off to find help.
When she gets back to the house, she finds a stranger in her house with her brother—she immediately recognizes him as Wolff, the guy who killed her mom.
When Wolff asks Sig and Anna where the gold is, he gets frustrated when they don't know. He threatens them a bunch of times, they really don't know so this doesn't change anything answer-wise.
Wolff ties Anna up before heading out to the ice with Sig. They grab the papers and Bible, and come back to the house.
When the gold is nowhere to be found, Wolff figures he'll use Anna for more than just money and prepares to rape her—Sig frees her just in time. Phew.
Anna and Sig book it, with Wolff chasing after them.
Fifty years later, Anna meets up with her brother and comes to understand that Sig chose not to kill Wolff that fateful day in their cabin.
She declares that it's important to remember that you always have a third choice, and then Anna runs off.
