Seven people fall into a sinkhole. Who will emerge from the horrors they now face?
Jerome Barrett, looking forward to some time spelunking with his mates? June Hicks, worrying about getting her son to school on time? Gertrude Williams, wondering why her husband hasn't told her about his visit to the doctor? Martin Collier, who wants to 'man up' his brother?
As fate throws them together, the life-threatening situation makes their everyday concerns appear trivial.
Fighting for survival is now their only option.
