The relationship between Bald Qiang (voiced by Tan Xiao) and his father (voiced by Meng Yutian) has never been very good. The two live in two different places and rarely contact each other. On this day, Bald Qiang's father suddenly came to Gou Xiongling to visit his son. Although his father took good care of Bald Qiang, the two people with different values soon had a conflict. When the father and son had another fierce quarrel, Bald Qiang and Xiong Da (voiced by Zhang Wei) and Xiong Er (voiced by Zhang Bingjun) were accidentally reduced in size by the "shrinking machine". Bald Qiang's father, who didn't know the truth of the incident, thought his son was missing and was very sad, so he chose to leave. What he didn't know was that he accidentally took the shrinking machine away. In this way, in order to restore the original size, Bald Qiang took the two bears and started a journey to find his father. The three people who were reduced had to face difficulties and troubles that they could never imagine in normal times.
