In the summer of 2018, a club in Beijing reorganized an ice hockey team consisting of a group of children born in 2009. Although they are only nine years old at that time, they have all played ice hockey for about four years. No.66 is a little but reckless and careless athlete; while No.95 is very active but without any hobbies in sports but ice hockey. No.97 is dreaming of becoming a professional athlete. Meanwhile, the focus of every family shifted around this little ice hockey. Two scenes and different tastes are entangled between children and their parents. Is ice hockey just a hobby or could be a possibility of being a career path? Will the children stay at home or study abroad for further practice? The story is happening silently. When confronting the dilemma, they all have the first taste of growth.
