An escapee from a psychiatric hospital sets fire to a flock of geese and then incinerates a passing hiker. And he's far from finished. While investigating, Wallander is unexpectedly visited by Anna, an old friend of his estranged daughter, Linda (Jeany Spark, "Sherlock"). Then Anna disappears. As more arson attacks occur, it appears that Anna may be connected and that Wallander must reconcile with Linda and join forces to find Anna at all costs. Father-daughter concord is hardly helped by Linda's memory that her dad once had an affair with Anna's mother.
