A 6-month-old girl becomes unresponsive in her crib, and stops breathing on the way to the hospital. Dr. G knows that the cause of death in infant cases is often elusive, and the baby's recent cold is the only potential clue.A 34-year-old man visits the hospital for severe abdominal pain, which the doctors believe is benign symptom of the man's recent cocaine binge. The man is sent home when the pain subsides, but the man falls ill and dies two days later. The man's wife claims that he has not used cocaine since the incident, and believes the hospital missed a key diagnosis. Could the wife be correct, or did her husband's cocaine habit finally catch up to him? It's up to Dr. G to find out.
