Alex's sister has gone missing and a body was found at the scene. Alex begins receiving mysterious notes leading her to believe Ukrainians have kidnapped her sister. However, the Ukrainians also want Alex dead since she knows about their plot. Alex must follow the clues in the notes to find her sister, but it's unknown if the note sender is helping or setting a trap for Alex. The filmmakers drew inspiration from British crime dramas and films like "88 Minutes" and plan to film in local Bristol areas to feel realistic. They aim to appeal to their target male audience aged 15-20 through action scenes and rewatchability.
