On the night she becomes an adult, innocent Neve must go to live in the underground caves that are home to a pair of monstrous Yeti. The Yeti claim her and tell her that there is one rule: She must not try to escape.
Rebellious Neve doesn't listen and ends up bound in an icy cell. Neve concocts a plan for freedom but it involves offering the Yeti the only thing she has to give...her body.
