Freshman male college student Su Yan suffers from a hereditary blood coagulation disorder, but after getting heatstroke during physical training, he was mistaken for feigning illness. His girlfriend and coach Lu Qinglan, along with his childhood friend Song Jiayan, locked him inside a high-temperature equipment room. In the critical moment, a cleaning uncle smelled blood, and security guards decisively broke open the door, rescuing him back from the edge of life and death. With the truth brought to light, prejudice and harm faced legal accountability, and the school carried out rare disease popular science and first-aid education. Under the care of relatives, friends, and society, Su Yan recovered and learned to seek help bravely; Lu Qinglan also reflected and made amends. Life allows no neglect, trust requires commitment, and a timely helping hand can light up the light of desperation.
