After his last experience, WéiLíng wants to master CPR and defibrillator use. Huy agrees to be his practice dummy, and the two take turns "rescuing" each other. When Huy applies the defibrillator paddles on WéiLíng, something goes horribly wrong! A surge of electricity unexpectedly stops WéiLíng’s heart. His body goes limp, his breath fades—this is no longer practice. Now, it's a real emergency. Huy must act fast. He loosens WéiLíng's clothes, presses his hands firmly onto his chest, and fights to bring him back. Every second counts—will Huy’s CPR skills be enough to revive his friend before it’s too late?
