Ian Gray, a PhD student studying molecular biology with a specialty in eye evolution, leaves his lab to go to a party and has an intense, but fleeting, encounter with a mysterious, masked model who escapes into the night. With only a picture of her stunning and iconic eyes, he tracks her down, and they fall in love. Their fundamentally different beliefs about life only serve to intensify their connection, and they vow to spend forever together. Years later, Ian and his lab partner, Karen, make a stunning discovery with profound existential implications. He must risk his life's work and his family to travel across the world to find the truth behind what he has found and what it may mean.
