Film and opening sequence synopsis

Opening Sequence:

A young woman is seen looking out of a window, we see her from behind, and then from the side, allowing us to view her profile. She jumps up before we see a mixture of brief clips showing the girl getting ready...we see her kiss a young man on the cheek before picking up her camera and leaving the house. The voiceover starts as we see more short clips of the young woman walking in an isolated area taking photos of the landscape. We see a shot of her walking past a MISSING poster of a young boy. She soon returns home to find the boy sitting downstairs waiting for her, she leaves her camera on the table and then walks out of the room, quickly pursued by her male counterpart.
