Lauren is a hardworking college student. She has lost her family after a biological attack where she lived. Those who survived that experiment are now called "immigrants". Desperate after the unfortunate events that befell the immigrants, the young girl marries a widow with a small baby in exchange for her health and education expenses. How will Lauren, who on the outside appears to be married to a wealthy man and lead a comfortable life, cope with her increasingly frequent and life-threatening hallucinations?
