The stingy boss suddenly generously gives out eighty-eight thousand in work red envelopes, and the whole staff falls into a frenzy, except for eight-year veteran employee Su Wan, who senses something is wrong at a glance—the company loses money month after month, and a person stingy to the core could never bleed a fortune. She resists the temptation and resigns on the spot, while her best friend stubbornly stays for her father's lifesaving money. Who would have thought that as soon as the red envelope is received, the best friend mysteriously loses contact, and the entire company falls into collective silence. Behind the abnormal welfare lies a fatal trap that bears thinking about with terror.
