Operating alone in the field for more than 20 years, a CIA hitman (Aaron Eckhart) uses the “Help Wanted” section of the newspapers to get his orders from the Agency. His long-lost daughter (Abigail Breslin), now a UK MI6 analyst, tracks him down to deliver shocking news: his CIA boss (Tim Roth) has been dead for years and the division long since shut down. Together, they set out to discover whose orders he's been executing.
