This dramatized biopic starts with Singh’s childhood in Shahabad. Since everyone around him (including his elder brother, Bikramjeet) is playing hockey, Sandeep joins their league by default. He soon starts looking for excuses to not go for practice because his coach has a rather rude way of teaching his students. Kartar Singh (the coach, played by Danish Hussain) who is supposed to inspire young guns to help India shine in the national game, actually makes Sandeep repel from hockey. So Singh starts spending most of his time at his uncle’s farm, flicking stones instead of a hockey ball to keep birds away while his elder brother Bikramjeet (Angad Bedi) takes the coach’s ways in his stride and excels in hockey.
However everything changes all of a sudden. Bikram misses his chance at the selection. Sandeep gets infatuated with Harpreet (Taapsee Pannu) who is Kartar Singh’s niece and a hockey player. He decides he will play hockey - but when a life-changing event happens, will he still play? Will he play for his love for Harpreet, like he did before, or his love for his country?
