On his birthday, Sheng Lin receives a pink sports car from his girlfriend. The two set out for a drive, but their journey is interrupted when another driver illegally changes lanes and rear-ends their car. Not only is the culprit rude and aggressive, but he deliberately dirties the vehicle and later teams up with his mother to shirk responsibility and refuse to pay for the damage. Sheng Lin and Liu Ruyan stand by their principles and protect their rights with clear evidence. What should have been a minor repair turns into a costly ordeal when the culprit insists on having the damage assessed by a professional agency, ultimately paying a hefty price for his ignorance and arrogance. From then on, the couple use kindness and courage to help others facing difficulties, standing up to misconduct with reason and promoting the positive values of following rules, acting responsibly, and daring to speak up, all while safeguarding civilized road behavior.
