The Final Suspects

Lao Jiao, a struggling construction worker works hard to make ends meet and provide for his daughter in high school. He is asked to leave the garage that he was renting by the owner as the Fire Department had begun issuing fines to such tenants. Back in the time loop, Xiao He Yun and Li Shi Qing decide to investigate the two remaining passengers -- a lady with a red plastic cover and Lao Jiao. Shi Qing approaches the lady in the guise of asking for sanitary pads, but her unflinching attitude removes their doubts about her. Lao Jiao, who had them in his suitcase, opens and offers the pads to Shi Qing, proving his innocence. He Yun approaches the lady with the cover to confirm their suspicion; she pulls a plug and explodes the bomb. Once again back in the time loop, Shi Qing and He Yun decides to attempt to save the passengers. They are fatally stabbed by the lady, who then proceeds to detonate the bomb. The time loop begins again and Shi Qing attempts to snatch the red cover for the last time. The lady tries to stab her, but He Yun blocks her. A brief scuffle follows and he stabs the lady. Dazed, bloodied and shocked, he leaves the bus with Shi Qing. It explodes behind them.
