Copy-store clerk Jerry Shaw (Shia LaBeouf) and single mother Rachel Holloman (Michelle Monaghan) are mysteriously "activated" into a secret, illegal mission by a cell phone call. Neither wants to comply with the female voice giving them dangerous directives via phones and digital signs, but "she" has framed Jerry -- who's now a suspected terrorist -- and threatens to kill Rachel's son, who's on a school trip to D.C.. While Jerry and Rachel go around Chicago committing felony after felony as instructed, an FBI agent (Billy Bob Thornton) and Air Force investigator (Rosario Dawson) try to figure out why this seemingly normal duo have turned into super criminals.
