The team boss Zhou Donghai (Qiao Shan) and his wife Huo Meimei (Ma Li) accidentally travel with their daughter Zhou Weiyu (Zhang Jingyi) and her boyfriend Wan Yifan (Fan Chengcheng) on a trip to visit relatives in an unfamiliar way. Zhou Donghai decided to take this opportunity to give his future son-in-law a comprehensive and no-dead-angle inspection. Wan Yifan also used his life to interpret what a textbook-level rollover is. Along the way, they encountered the RV accident of Director Jia (Tian Yu), Zhou Donghai's mortal enemy and "professional troublemaker", the drunken farce of Weiyu's "childhood sweetheart" Guangzi (Chang Yuan), and the siege battle to capture the highway thieves "Oil Rat". The chaotic trip to visit relatives was full of embarrassment and laughter!
