Plot summary
The team receives the number of Maria Martinez ( Nazneen Contractor ), an engineer working for the international energy company HydralCorp. Maria is working to clear the name of Omar Risha ( Haaz Sleiman ), a man from Iraq suspected of being a terrorist. Shaw, Fusco and Reese save Maria from an assassination attempt and learn that Omar was her translator in Iraq and saved her from a terrorist ambush during the shipment of six generators. The generators went missing and Omar learned about their disappearance, being targeted for it. Finch learns that the generators were shipped elsewhere and that HydralCorp's corrupt CEO Ken Davis ( Casey Biggs ) is responsible.
Maria and Shaw discover that Davis has created a false report of Omar's terrorist accusations, and that French United Nations diplomat Rene Lapointe ( Michel Gill ) has the papers approving Omar's asylum in the US in his office. Reese, Fusco and Omar break into the UN building and stop Greek diplomat Christos Sevon ( William Abadie ) from killing Maria. Root takes Bear to spy on Decima head Greer, where it is revealed that Davis had the generators shipped to the US so Greer can power Samaritan. Greer has Davis killed and leaves, and Root follows him.
