On Antique Street, everyone considers Fang Ye a useless shop assistant who earns just 3,000 yuan a month sweeping floors and serving tea. Chamber of Commerce President Ma Dashan publicly smashes a bottle and forces him to sign an agreement stating that if his appraisal is inaccurate, he must compensate him with the shop. Nobody knows that this quiet shop assistant is the sole inheritor of a deceased master counterfeiter, whose eyes can see through every fake under heaven. When a three-year-old sealed case involving the substitution of a national treasure resurfaces, and a rubbing left behind by his master before death comes to light, the entire street accuses him of forgery and theft. He gives just one answer: 'This bottle is fake. I won't pay a single inch of this shop.'
