Little hamster Qiaoqiao accidentally gets lost and stumbles into the yard of Chen Pi, an orange cat. Seeing Qiaoqiao scared and helpless, the hard-hearted yet soft-spoken Chen Pi decides to send her home. Along the way, they meet the enthusiastic and clumsy Danjuan, and receive help from partners like Damai and Baicha. Following Qiaoqiao's memories of the fountain square and the blue house, they keep searching. Although they take wrong turns and experience twists and turns along the way, they never give up. Little companions who were originally strangers build a deep friendship through companionship and mutual encouragement along the way, and also make Qiaoqiao gradually become brave.
