A disgraced and deranged scientist (Val Kilmer) traps six sexy strangers in a hotel steam bath and slowly turns up the heat. It's all to prove that humanity will go crazy under the pressures of global warming. It seems that chaos will be averted when Detective Mancini (Armand Assante) discovers what is needed to free the hostages.

However, it doesn't take long for the fear and paranoia to boil over, leaving a bloody trail in its wake. Also starring Eric Roberts, Megan Brown and Patrick Muldoon.
