In order to repay his gratitude, stray dog Xiao Qi traveled a long way to the pet resort. Who knew that his benefactor Ou Ye (played by Wang Yang) had long forgotten the "past" between them. For Ou Ye, Xiao Qi was just a nasty guy who was overly enthusiastic about him and caused trouble for him everywhere. Ou Ye has always been secretly in love with the lifeguard Bao Yu (played by Zhang Yunlong). Xiao Qi sensitively noticed this feeling and became hostile to Bao Yu. There were many jokes between the man and the dog. In the end, Xiao Qi accepted Bao Yu's existence and helped Ou Ye win Bao Yu's recognition and love. At the same time, with the help of Ou Ye, Xiao Qi also got the opportunity to perform on the same stage with the star Border Collie Mary, realizing his dream. Just when the family was having fun, a group of underwater cultural relics theft gangs targeted the cultural relics in the sunken ship in the resort's waters, and the danger was approaching step by step.
