Mr. Fox and his wife, Mrs. Fox, are caught in a trap as they steal chickens from a farm. As they hear the Farmer approaching Mrs. Fox tells her husband that she is pregnant and if they ever get out of this situation she wants him to go straight. We cut to the future where Mr. Fox and Mrs. Fox are now living in a underground den with their son, Ash. Mr. Fox begrudely writes for the local paper. He wants to move to a tree, above ground.
The ‘Inciting Incident‘ occurs when Mr. Fox goes to see a ‘tree’ property and sees that outside the window are three farms (owned by Boggis, Bunce and Bean). He decides to go back to his old ways of rustling and do one last job.
After moving into the tree, Ash is made jealous by the arrival of his cousin Kristofferson who seems to excel at every thing. Meanwhile Mr. Fox enrols the help of a possum, Kylie, to rob the farm of Boggis where they escape with a bounty of chickens.
Mr.Fox moves onto robbing the farm of Bunce now enroling the help of Kristofferson.
After all three heists are a success, the farmers decide to camp out near the Fox family’s tree and kill Fox. When he emerges, the farmers open fire, only managing to shoot off his tail before he retreats back into his home. The farmers then attempt to dig Fox out, first by hand and then with three excvators. After tearing the hill site of the tree into a massive crater, the farmers discover that the Foxes have dug an escape tunnel deep underground.
