Lyndsy Fonseca ('Kick-Ass') and Linda Hamilton ('The Terminator') star in this metaphysical time travel thriller. Helen Phillips is a young engineer struggling with the heartbreak of the recent suicide of her husband, a physics genius and co-founder of Curvature Research. He was on the cusp of his greatest professional triumph - a time machine prototype shrouded in secrecy - until his long-simmering depression became uncontrollable. Helen’s grieving is interrupted when she wakes up one morning, disheveled and panicked, with her memory damaged. The phone rings and a voice, sounding uncannily like her own, warns her that she’s in danger. Soon, Helen is on the run from unknown pursuers while she follows a trail of clues she seems to have left for herself to find. She quickly realizes that she has traveled thirty-six hours back in time, but why? Is it to uncover the truth about her husband’s death? Or is it, as she soon suspects, to stop the past version of herself from committing a violent and irreversible crime?
