Helpless - 2012 - 7/10
AKA - Hwa-cha // 화차

Well paced Korean mystery.
Enroute to introduce his fiancée to his family, the boyfriend stops at a gas station for coffee and snacks.
Inside the car, the girlfriend answers her cellphone.
The boyfriend returns to an empty car.
He cannot find her. The police are uninterested, dismissing it as bridal jitters.
The boyfriend hunts harder, discovers she was not who she claimed. His fiancée was an imposter.
Eventually he hires a friend / relative (?), ex-police to track her down.
All that occurs early on in dark, downward spiral of a tale.
Solid mystery / thriller. Absorbing date flick, especially if your partner keeps secrets.
