A delivery worker faces malicious harassment by security guards, being forbidden from taking the elevator and forced to climb 48 floors to deliver food. When delayed, he gets soup splashed on him by the customer, and later has his vehicle locked, gets beaten up, and suffers humiliation. Station manager Chen Yan stands up for his subordinates to fiercely confront the property management, directly halting all new orders for the entire building. The management secretly shifts blame and smearing him, but Chen Yan holds irrefutable evidence to strike back publicly, making the hypocritical manager and arrogant security guard reap what they sow. An elevator exposes human nature; dignity is never charity, but won by oneself.
