At first, the children refuse to listen and carry on fighting, which Nanny McPhee soon puts a stop to with her magic, making them hurt themselves like they did each other and even destroy items, including nearly throwing letters sent by Rory while he’s away. Luckily, everything is put back to normal after the children apologize to one another. Meanwhile, Isabel’s brother-in-law Phil has gambled away his half of the farm, and is being chased by two hired female assassins working for a casino owner named Mrs. Biggles. Phil desperately attempts to make Isabel sell her half of the farm, including setting loose the litter of piglets to be sold to a neighboring farmer, but the plot is thwarted by the children, leading them to bond as they work together to recapture the pigs.
