Plot: Disasters investigated include: the 1984 Union Carbide debacle in Bhopal, India, where a toxic chemical release killed 3,800 people and left 11,000 with disabling respiratory ailments; and the 2003 sudden collapse of a 10-story parking garage at the Tropicana in Atlantic City, New Jersey that killed four and injured 20. We find out why a series of structures in Hutchinson, Kansas mysteriously caught fire and exploded in 2001; and examine the 1933 construction of a canal ordered by Soviet dictator Joseph Stalin that later proved to be nearly useless and cost many lives
