Full spoiler of Wideacre from start to finish:
Spoiler
Beatrice dated Ralph. They plotted to kill her father. Beatrice's brother Harry would inherit the house. They would steal and cheat Harry until he was forced to sell the house, then they would buy it. But instead, after Ralph killed the father, Beatrice tried to kill Ralph. She almost did it, but he got away. Beatrice then started sleeping with her brother Harry. Harry got married to Celia. Beatrice got pregnant by Harry. Gave birth to Julia. Pawned Julia off on Celia. Beatrice got pregnant again. Got married to John. Gave birth to Richard. Tried to pretend the baby was John's, but Richard was born much too soon and too big to be John's. John started to drink. Beatrice and Harry's mother caught them together in bed. Before she could talk, Beatrice killed the mother. She framed John for it and said if he ever went against her, she would have him hang for it. John drank more. Beatrice encouraged his drinking. Then she had him committed and took over his money. Celia ended up being barren. Since Harry had no legitimate son, a cousin was going to inherit Wideacre. Beatrice used John's money and took out a bunch of loans to pay off the cousin and to hire lawyers to make Julia and Richard the ones to inherit. That was a success. But then she was falling behind on the loan payments. A lot of farmers lived on their land. She started working them to the bone, threatening to tear their houses down if they didn't work more for less. People started dropping like flies of starvation, suicide, etc. But she kept going. John got out of the hospital. John and Celia started getting really close. They were the only ones who cared about the farmers and also the children. Beatrice just wanted her blood to inherit, she didn't actually care about the children. They tried to help the poor as much as they could. But John and Celia weren't able to do enough for the poor with Beatrice and Harry working against them. Then Ralph came back. He had made a name for himself as "The Culler" by taking down any corrupt landowners. John, Celia, Harry, and the children ran. Beatrice stayed in the house. Ralph came for her, killed her, and burned down the house. Harry died from fright while running (bad heart ran in the family, and he was overweight too). John, Celia, and the children moved into a cottage on the land, and the farmers went back to their old ways, and everything was good again.
