On the way home from a seemingly fraught Thanksgiving dinner with her parents, Ray (Sam Worthington) and Joanne Monroe (Lily Rabe) pull over at a gas station so their six year old daughter, Peri (Lucy Capri) can go to the bathroom. Here Peri falls in an open construction site and breaks her arm. Ray rushes them to the hospital and Peri is taking for a CAT scan accompanied by Joanne. When his family fails to re-emerge, Ray becomes convinced that the hospital has done something nefarious to them but there’s no record of their admission.
