Above them in their small town, their families, friends and neighbors busy themselves with their everyday routines - complete with petty squabbles and arguments.

At a time when the whole community must come together as one to help those trapped by the disaster, deep-rooted prejudices are allowed to resurface threatening any hope of the collective rescue effort that is required to save the miners.
