Five‑year‑old Ollie possesses a magical superpower: whatever he plants can grow into giant objects or crops. Struggling in poverty, single mother Emma lives with him on a run‑down old farm. After growing giant pumpkins, a money‑bearing tree and oversized farm tools, they gradually build up their farm and make a living by selling special giant produce. Greedy Pete covets their land and keeps trying to seize the farm. Later, Emma’s estranged husband Daniel appears. He figures out that Ollie is his biological son and attempts to win custody of the gifted boy by taking advantage of legal loopholes. Through countless dangers and conflicts, mother and son preserve their home, defeat malicious opponents, and finally gain quiet, peaceful farm life of their own.
