Nicholas Spencer, president of the company that developed the cancer vaccine, crashes in his personal plane. Two weeks later, it is discovered that there is no miracle vaccine, and the company is on the verge of collapse. Since Nicholas's body has not been found, no one believes he is dead and he is accused of fraud. Lynn Spencer, Nicholas's wife, nearly dies in a fire when someone sets her house on fire. Trying to find out the truth, her half-sister, journalist Marcia DeCarlo, begins her own investigation.
