This time, we meet a man who feels no pain, a woman who can smell Parkinson's disease, a man who can remember every face he has ever seen and a survivor of a head injury who woke up to find he could suddenly play the piano.

This time, Gabriel uncovers the stories of a man with bones as strong as granite, a woman who became pregnant with twins in two separate wombs, a girl whose arm won't stop growing and a woman who gets lost in her own home.
