Through a Glass Darkly concerns a psychologically fragile woman, Karin (Harriet Andersson), who seeks recovery from a nervous breakdown while on a remote-island vacation with her family. Unfortunately, her father (Gunnar Björnstrand), a successful writer, regards her with clinical detachment, her husband (Max Von Sydow), a doctor, feels unavailing in the effort to treat her, and her brother (Lars Passgard) is wrapped up in his own quest for sexual fulfillment. Karin's descent into further loneliness and delusion exacerbates the heretofore unspoken alienation at the heart of this entire family, and drives the characters to brood over the existence of God (or, in Karin's case, imagine that God is the chilling spider hidden behind an attic door). Through a Glass Darkly is a heartbreaking, powerful work of art.
