In criminal court, delivery worker Song An faces unjust accusations. Overcome with emotion, he stands tall and bursts into tears in front of everyone. The story rewinds to three days earlier, when Song An learns that his mother's condition is critical and that she needs 100,000 yuan for medical expenses. While making a delivery in the pouring rain, he witnesses Pei Mingyue lose her footing by the river. Without hesitation, he abandons his bike and jumps in to save her, with the moment frozen in slow motion as he hangs in midair. Yet his act of kindness is twisted into something sinister, and a chain of evidence points toward a misunderstanding. Trapped in desperation, can Song An expose the truth and turn the tables? This battle between goodwill and justice gives us much to reflect on.
