A strange incident occurred in a place in Northeast China. All the sheep of villager Xie Yifei disappeared overnight without a trace. His plan to marry the widow Dajuan was ruined by the mischief of his grandson Xie Xiaoxie and his rival Wang Erzhou. In order to find out the trace of the sheep, Xie Yifei embarked on a search, but was unexpectedly kidnapped by the alien Moji on the way. As a result, he accidentally learned that the alien wanted to move the village to an alien planet for exhibition. Xie Yifei escaped from death and returned home to inform the villagers to evacuate urgently, but was misunderstood and ridiculed by everyone. In desperation, Xie Yifei could only protect the villagers himself, thus launching a hilarious "Earth Defense War".
