Businesswoman Vivian VanArp is the CEO and sole heir of VanArp Enterprises, a giant healthcare conglomerate. She is under consideration as the vice president in the next presidential election. Most importantly, she funds world-leading research on ageing. Everything in her life is perfect, until the night she receives a call from the hospital.

An old woman who is nearing death claims to be Vivian's housekeeper, but Vivian knows this is not possible. Her housekeeper is twenty-five years old, and the woman in the hospital bed is at least ninety. The invalid makes a request of her that Vivian doesn't understand. It frightens the heiress and she rushes away from the hospital, the old woman's key clenched in her fist. With mysterious words in her head and the antique key, Vivian races to secure one of the greatest discoveries in the world for herself. Unknown to the businesswoman, she has stumbled upon a centuries old secret—a mystical substance that at least one person is willing to kill for, again and again.
