Norwegian sisters Nora (Renate Reinsve) and Agnes (Inga Ibsdotter Lilleaas) reunite with their estranged, charismatic father, Gustav (Stellan Skarsgård), an egotistical filmmaker attempting a comeback. When Nora rejects his script, Gustav casts a young Hollywood star (Elle Fanning), forcing the complex family to confront deep-seated trauma and art's boundaries.
