Description:
Ten half-conscious seconds are all a woman remembers from her kidnapping. Small clues linger in her broken memory, clues she hopes will be enough to identify the kidnapper. A police officer takes her under his wing and together they begin an unconventional investigation, using what little she knows to track down their suspect. As her memory fades, truth begins to meld with fiction. Time is running out. Will she remember? What will she remember?
