Synopsis：Cui Ying, the former teen judo champion of Bangkok, now works as an employee at a local small bank. On the night of the Mid-Autumn Festival, she stayed late at the bank. After finishing her work, she hurried down to the garage but found her car had broken down and wouldn't start. Her phone had no signal either. At this moment, Cui Ying sought help, but she secretly discovered that the security guard and a group of criminals were colluding, planning to steal the old banknotes about to be destroyed during the bank holiday when no one was around. Cui Ying, having learned this secret, was brutally struck on the head and fell unconscious. When she woke up, she found herself tied up in the security guard's office. Clearly, Cui Ying would have to rely on her own strength to escape from this nightmarish underground garage...
