Ariel Smith's world turned upside down when she fell down the stairs two months prior, resulting in permanent blindness. Her father, Daniel Smith, was diagnosed with a terminal illness around the same time. Feeling his time running out, Daniel hired tough-as-nails underground boxer Zach Swanson to protect Ariel, offering a substantial payment for his services. Zach's job was to keep Ariel safe from harm, but tragedy struck when Daniel was killed in a car accident shortly after signing the contract.
