Liu Qiang, owner of a small-town fresh fruit shop, runs his business steadily and depends on his mother for mutual support. Who would have thought that his vain distant aunt, Xiulian, would mistake a travel agency owner with the same name for him, and for just a 5-yuan registration fee, drag more than twenty relatives into signing up for an "internal tour group." During the trip, she extravagantly overdraws her consumption, using Liu Qiang's signature to run up a bill of 176,800 yuan. After the matter is exposed, Xiulian refuses to pay the debt and actually expects her nephew Liu Qiang to pay it back for her, while at this moment, Liu Qiang, having gathered the evidence, begins his true counterattack.
