Tasia is stuck in a cycle that ends on the 21st.
Whenever the bell strikes the early morning of December 17, 1991, the base will self-destruct, and she will disappear into the corner of Siberia along with the base.
But once she dies, she will go back to 21 days ago with her memories and enter the cycle again.
For the 99th time, she finally found the key to break out of the cycle.
Intention: Self-salvation.
