A volcano beneath New York City seems unlikely...yet nothing else can explain the bizarre tremors and terrifying explosions wreaking havoc on the city. Tunnel digger Matt MacLachlan (
Costas Mandylor) and his team of "Sandhogs" have witnessed lava seeping into the city's aqueduct system and know the unimaginable truth. A scientist's (
Michael Ironside) secret, geo-thermal experiment has triggered the volcanic activity; and now Matt, his geologist ex-wife (
Alexandra Paul), and a team of unlikely heroes have only a few sticks of dynamite and a prayer to rescue the city from volcanic apocalypse.
