They end up in a hotel in a European city, where Roy tells June not to leave the room. Still suspicious, she follows him to a meeting where Roy makes it seem that he has the perpetual energy battery and is willing to sell it. June feels betrayed. She is grabbed by the CIA and told that Roy is a rogue agent. When she is with Roy and the battery, she must alert them by clicking a radio-pen.
So, Roy returns and June clicks the pen. Agents show up and Roy is chased across the rooftops before he is shot and falls into the sea. They never find his body.
June returns to her normal life, she goes back home and is a bridesmaid at her sister's wedding. She remembers seeing an address on Roy's PDA - and when she checks it out realises it belongs to Roy's parents, who have been secretly cared for, and believe their son died in the military.
June pieces things together, and then figures that Roy knew she would follow him and said those things at the meeting before so she could return to a normal life, guilt-free.
She leaves a message on her phone, knowing it has been bugged, and is soon captured by the Russians. She is rescued by Roy, with the getaway being the motorbike scene from the trailer riding among a bull race through the city streets.
Meanwhile the dodgy FBI agent is taking the scientist to a safe house, but shoots the driver and kidnaps the boy. Miller meets up with him for a deal - he throws the bad guy the hot battery, but takes a bullet to protect the young scientist.
The rogue FBI (or CIA? I can never figure which) agent makes it away in a sea-plane - but the battery is chemically unstable and explodes.
Miller is in hospital, where the Director apologises for what happened - but suggests that he will be killed to clear up their mistakes. He is drugged - but the nurse is June. She gets him out and they drive to Cape Horn - where they will meet up with Roy's parents who think they have won another free trip.
Would have been better for the movie if she was called June Day. Nevermind.
