>>211390647 (OP)Widow married a rich man who she thinks will elevate her and her kids to upper middle class status and give her kids a bright future... But he's evil jncarnare, basically tortures her kids and tells them repeatedly that he doesn't love them and only cares about them in the abstract of literal hostages to force their mom to be trapped in a hellish marriage where he treats her like a literal slave since the court system at the time automatically gave custody of kids to their dad.
The kids eventually use Jewish magic to murder their evil stepfather to free themselves and their mom but the final scene show that the son at least, will be forever haunted by the memories of the abuse he suffered.
