Character-driven thriller about the hostage situation that develops after a tech tycoon (Jesse Plemons) and his wife (Lily Collins) pay a spur-of-the-moment visit to their lavish country house only to find it occupied by an armed intruder (Jason Segel). As the trio waits for the ransom money the mogul eventually agrees to pay to arrive, class conflicts emerge. So, too, does marital friction. Working from a script by Justin Lader and Andrew Kevin Walker, director Charlie McDowell serves up a thinking person’s suspense drama that, while it lags somewhat in the middle, reaches a startling conclusion. Although the depiction of criminal mayhem is mostly restrained, there are a few disturbing moments to be endured and tension leads to much nervous swearing. A gruesome death, other brief but intense violence with gore, a few profanities, a couple of milder oaths, pervasive rough language, a handful of crude terms.
