In The Friend, writer and teacher Iris (Naomi Watts) finds her comfortable, solitary New York life thrown into disarray after her closest friend and mentor (Bill Murray) dies suddenly and bequeaths her his beloved 150 lb. Great Dane. The regal yet intractable beast, named Apollo, immediately creates practical problems for Iris, from furniture destruction to eviction notices, as well as more existential ones, his looming presence constantly reminding her of her friend's problematic choices in both life and death. Yet as Iris finds herself unexpectedly bonding with the animal, she begins to come to terms with her past, her lost friend, and her own creative inner life.
