After the world has been being radiated in 3023, the first survival, a woman in her forties, had to accept her fate that she would never see her daughter again, but the emergence of some kids from an underground bunker renews her hope, and she wants to find her even if the earth is uninhabitable and the search can be dangerous.

Tasya Clearlake and her daughter used to live happily. They only have each other and her grandfather, Professor Jafechandler, as her husband died as military personnel on a mission some years ago. Tasya, a manager at a big pharmacy, supports her daughter in everything and helps her as much as possible, though it’s hard work to parent alone. Then, one day, radiation catches everyone at different places at a time. Tasya was at work, and Alanna was at school. This is the end of the world. Except that, not every human died in the radiation.

Tasya survives. She is one of the lucky few. At first, she thinks she is the only one alive in the whole world. Every day, she contemplates suicide and finding her daughter, who is likely dead. A few months later, some young adults emerge from an underground bunker. When Tasya sees them, she thinks her daughter might still be alive and sets on a mission to find her with the help of one of the boys who just emerged from the bunker.
