A woman in a happy marriage with two kids meets another man at the grocery story and unexpectedly falls in love. She divorces her old husband and marries the new man, who also divorces his former wife. Now the new couple has four children to look after, two from each marriage. The woman doesn't like how messy the children are, and questions the parenting style of her partner's ex-wife. The ex-wife resents both of them and uses the kids to retaliate, dropping them off at unscheduled times and making up appointments and excuses. One night, right as the woman and her new husband are about to spend the evening at the opera, the ex-wife dumps the kids on them. Furious, the woman changes out of her nice dress into exercise clothes and heads out "for a run." She walks to her husband's old house and looks in to see his ex-wife relaxing on the couch. She thinks about knocking on the door and starting a fight, but she decides against it. The woman's husband convinces her to do something nice with the children, so they take the four kids to a cabin for a weekend in the woods. The woman's two children bring books while her step-children bring video games, but the cabin doesn't have Wi-Fi. The husband takes the kids outside and plays with them until they're worn out. The woman falls asleep convincing herself that everything is fine, but she wakes up in the middle of the night with the sudden urge to abandon the children. She wakes up her husband and convinces him to go with her, to come back when the children have grown. They take off and return to their apartment, where they drink, smoke, and have sex. They sleep for a few hours. The woman imagines the future of the children, how they'll learn to fend for themselves, foraging, hunting, and making their own clothes. She pictures the older boys killing a deer but not knowing how to safely cook it. Eventually, they will grow up and the woman's daughter will marry one of her step-sons. The woman decides to go back to the cabin and arrives before dawn, in time to feed breakfast to the children. She goes about the rest of the day watching the kids play outside and then calling them in for dinner, fully accepting her role as a mother.
