Luke resigned himself to the thought of death, but a female voice could be heard beyond the wall. Eva, too, turns out to be a victim of the psychopath, just like Luke. Luke and Eva meet, argue, fall in love, and even dance, but what plans does fate have for them? Will they be able to escape captivity, or is this their final dance underground?
