Keith Miller is a busy single father who is constantly traveling to support his family. He receives a call from Dr. Stone, who informs him that his daughter, Hannah, has advanced-stage stomach cancer and has only a four-hour window for critical treatment. Keith immediately contacts his mother, Helen Davis, who helps care for Hannah, and instructs her to take the girl to Central Hospital. Worried about his mother's health, he withholds the truth about Hannah's critical condition and rushes to the hospital himself.
Because Keith is often away, a health supplement salesman named Gary Stevens enters Helen's life, claiming to be devoted to caring for seniors. He frequently helps with household chores and keeps Helen company, eventually being recognized by her as her "godson." Trusting Gary, Helen believes his advice that Hannah's stomach pain is simply due to irregular meals. She gives Hannah the stomach-nourishing supplements Gary recommends.
Unbeknownst to them, these supplements are adulterated with sleep-inducing ingredients. They temporarily relieve Hannah's pain, but this masks the true and critical severity of her illness.
To continue deceiving Helen and taking her money, Gary lies, telling Keith that Hannah has already been taken to the hospital so he will stop calling incessantly.
