How roots can both nurture and trap us is the subject of Wiebke von Carolsfeld’s finely observed Stay, based on the novel by Aislinn Hunter. Dermot (Aidan Quinn) is a historian reeling from a personal tragedy, who has isolated himself in a crumbling farmhouse on the rugged west coast of Ireland. His lover Abbey (Taylor Schilling, from the acclaimed series Orange is the New Black) is happy to hide out there with him. That is, until she realizes that she’s pregnant.
