At Balloch Moss mine in Scotland, water comes through a seam bringing a torrent of mud into the mine and flooding the pit shaft, resulting in 118 men being trapped, with nine missing. The only means by which the rescue team can bring the men out is through some old abandoned workings which are now full of gas and thus will cause delays in any rescue attempt.
