A man comes to awareness in a church in rural Iceland, not knowing why he’s there or how he arrived. When a local woman offers to reunite him with her sister, he realises he’s lost not only his bearings, but his memory as well: he doesn’t recognise either woman, and as their stories unfold, he is plunged into a history spanning centuries and lives: a city girl drawn to the fjords by the memory of a blue-eyed gaze; a farmer’s wife whose essay on the humble earthworm changes the course of lives; a pastor who writes to dead poets and falls in love with a stranger; a musician plagued by cosmic loneliness, who discovers that his life has been a lie; and an alcoholic transfixed by the night sky. Faced with the violence of destiny and the effects of choices, made and avoided, that cascade between lives, each discovers the cost of following the magnetic needle of the heart.
