Sweeney's complex tricky performance – mixed with the emotional stakes – makes this intriguing drama completely absorbing.

It’s a troubling, unsettling and beautifully made production, all the more notable for being a debut feature that rigidly adheres to the actual recording that the FBI men made on the day that a brave young woman lost her freedom.

Reality is a bizarre blend of the gripping and the banal -- a film in which politeness is used as a weapon and guile is disguised as embarrassment.

Sydney Sweeney revels in a dressed-down role whose internal conflicts and complexities show the acting mettle that was always beneath her bombshell reputation.
