But everything comes crashing down when her son, Josh, is diagnosed with a rare form of cancer.
Determined to save him, Emma makes the risky decision to sell opioids to fund the life-saving treatment he needs.

With her son’s life hanging in the balance, Emma is dragged into the dark world of drugs, lies, and murder. Will the truth catch up to her before she can save Josh?
