John and Eva investigate the murder of bullet-ridden body found in Chinatown. However, the body looks similar to Amsterdam's lost son from the 1900s, Roosevelt.
John Amsterdam is a New York homicide detective unlike any other. He is brilliant, mysterious, reckless, and immortal. In 1642 he saved a Native Indian girl during a massacre of her indigenous tribe. In return, the girl cast an ancient spell that conferred immortality upon him. Amsterdam will not age, she told him, until he finds his one true love.
