Wanjia Village suffers from years of drought. Cracked fields leave the villagers in dire straits. Local tyrants seize the only water source to exploit and bully neighbors. Kind-hearted villager Lao Quan spends all his savings and land to save a spirit carp trapped in a mud pit. His sincerity awakens the carp, which is the Rain God undergoing tribulation. It shares immortal water to help the villagers. The tyrants repeatedly try to steal the water and harm others, and their evil deeds bring retribution: the water turns to mud once it leaves the valley. The tyrants meet a miserable end. The Rain God survives the trial and sends rain, restoring life to the village.
