The series follows the title character "Osiris", a man with an eternally extended warranty on life. He can never stay dead. If killed, he resurrects in EXACTLY 37 minutes, every time. He has three centuries of knowledge, speaks 16 different languages and has traveled the world five times over. So he's a suave and handsome man who's become an apathetic, sarcastic, arrogant, tough-as-nails, womanizer. He's kept in line by his professional and driven great-great-Granddaughter, Paula Castleberry, and his only friend, Special Agent Gregory Barnes of the FBI. As the series begins, Osiris has only 24 hours to track down a kidnapped witness in a federal murder trial. His dangerous hunt not only unravels a conspiracy but it also unveils clues to the true nature of his eternal life.
