Before the wedding opening, the main stage lifting equipment suddenly malfunctioned. Wedding stage equipment technician Gu Chengye used a backup safety switch to save eighty-eight tables of wedding banquets, but was fined for not going through approval. From then on, he only acted according to regulations. Customer rushing, equipment chain malfunctions, colleagues shifting blame, and management passing the buck came one after another, and the wedding scene fell into crisis time and time again. Gu Chengye guarded the safety and process bottom line on one hand, while using records, testing, and on-site evidence to restore the truth, forcing the company to face procurement loopholes and responsibility attribution. Facing the pressure from the boss and the procurement manager, he finally made the wedding complete smoothly.
