A tranquil picnic in the English countryside shatters into tragedy for university professor Joe Rose, played by Daniel Craig, when a fatal hot air balloon accident draws him and a stranger into a harrowing rescue attempt. This single, shared moment of trauma becomes an inescapable bond for Jed Parry, a hauntingly intense loner portrayed by Rhys Ifans, who interprets the event as a profound spiritual connection. As Jed’s initial gratitude curdles into a dangerous and all-consuming obsession, Joe’s orderly life with his artist girlfriend Claire, Samantha Morton, begins to unravel under the strain of constant, unnerving attention. This gripping psychological drama, directed by Roger Michell, masterfully explores the dark edges of love, belief, and coincidence, trapping Joe in a escalating nightmare where his rationality is pitted against Jed’s deluded conviction, threatening everything he holds dear.
