Redemption
Redemption is an aura that comes once every a hundred years. Whoever enters the Aura once it's complete, will be cured from any kind of sickness and will be immune to any further infections. In this year, Ann has a sister who got infected by cancer and nothing seems to cure her. When the first signs of redemption appear, it's her job to get her sister over there as fast as she could, before the aura leaves for another hundred years.
