Lisa (Rachel McAdams) is in conversation with someone nearby when the atmosphere abruptly shifts, becoming unsettling. It’s revealed that Rippner (Cillian Murphy) wants her to reach out to the hotel where she's employed and arrange for a visiting family – one of significant importance – to be relocated to another room. Failure to comply with this seemingly straightforward request will result in someone on the ground being prepared to harm her father, Joe (Brian Cox). The film functions reasonably well as a thriller during its initial thirty minutes; the interaction between the characters, particularly Lisa’s confinement within her airplane seat, contributes to a palpable feeling of danger. However, once she starts resisting, the plot noticeably diminishes in impact. Rippner's firm grasp on events begins to unravel due to coincidences that feel overly convenient for my taste. It isn't wrong for Lisa to challenge her tormentor, but the way she does so stretches believability, leading to a rather chaotic and disappointing resolution that feels inevitable. Murphy is an actor who can convey a sense of menace – he possesses a certain appeal with an underlying air of deception (I believe he would be well-suited as a "Bond" antagonist), and McAdams delivers a performance that’s assured and capable; it's simply the story itself that becomes uninspired and ultimately falls into predictability.
