Our protagonist, the Old Man, is visited on his farm by grandkids dropped off for the summer. Determined to show them the simple beauty of country life, he ends up working them like slaves—until the little terrors accidentally release his prized (and thoroughly abused) cow. Now, with just 24 hours to recover the rogue bovine before her unmilked udder explodes and unleashes a "lactopocalypse"—or before the mysterious Milk Man finds and lethally disarms her—the Old Man and his grandkids embark on an epic quest. Along the way, they’ll face festival hippies, forest creeps, sawmill workers, and other hazards of the Estonian countryside.
