In northern Iceland, 1829, Agnes Magnúsdóttir is condemned to death for her part in the brutal murder of two men. Agnes is sent to wait out the time leading to her execution on the farm of District Officer Jón Jónsson, his wife and their two daughters. Horrified to have a convicted murderess in their midst, the family avoids speaking with Agnes. Only Tóti, the young assistant reverend appointed as Agnes’s spiritual guardian, is compelled to try to understand her, as he attempts to salvage her soul. As the summer months fall away to winter and the hardships of rural life force the household to work side by side, Agnes’s ill-fated tale of longing and betrayal begins to emerge. And as the days to her execution draw closer, the question burns: did she or didn’t she?
