On Hostile Ground is a 2000 television movie starring John Corbett. Directed by Mario Azzopardi, the film originally aired on TBS on June 11, 2000.

Matt has a number of personal issues because of a disaster which happened at a mine he was advising on its operations. Although cleared of responsibility for the accident, he still blames himself, which may be causing him to be overcautious. Matt admits the potential problem of the sinkholes becoming so serious as to endanger the city could occur next week, or not for three hundred years. Based on the lack of real evidence of immediate danger, and because some evidence that she should have received has been destroyed by the mayors political flack, Allison has decided not to close the festival, only to have the disaster metastasize, like a cancer devouring the citys underground.The only answer is to obtain several tons of polyurethane liquid incompounds which when combined produces an expanding foam that will fill the huge sinkhole cavern. The polyurethane expanding foam reaction will expand to hundreds of times its size, and becomes as hard as concrete. Due to an emergency, while Matt is underground inspecting the caverns, he becomes partially trapped, and has to ask to have the foam started which will kill him if he cant find an escape because if they dont start the flow of the liquid immediately, the ground underneath downtown New Orleans will collapse similar to the effects of soil liquefaction and thousands to tens of thousands of people will be injured or killed. The last few minutes of the film become a race against time as Matt attempts to find an exit before the polyurethane foam envelops him. ........
