Oliver Falk is one of the Denmark’s greatest hockey talents, raised on the ice under the shadow of his father, former star player and now coach, Lasse Falk. Wearing his father's name on his back, Oliver carries both a legacy and a dream: to succeed in hockey and make his father proud. But after sustaining an injury, his life on and off the ice begins to fall apart. Opioids become a shortcut — a way to keep up with hockey and to numb the pain. Momentum is a touching father-son story, set in an arena of adrenaline-fueled tackles and close-knit communities.
