Eighty-two-year-old Etta has never seen the ocean. So early one morning she takes a rifle, some chocolate, and her best boots, and begins walking the 3,232 kilometers from rural Canada eastward to the coast. Her husband Otto wakes to a note left on the kitchen table. Otto has seen the ocean, having crossed the Atlantic years ago to fight in a far-away war. He understands. But with Etta gone, the memories come crowding in, and Otto struggles to keep them at bay.
