Can not for the life of me remember that name of the movie I would guess the movie was made in the mid to late 90s I can remember pieces of the movie,the city is blowing up some cave with tnt or dynamite and they don't know there letting snakes loose.There killer snakes and this single mother of maybe 2 or 3 kids work with a police officer of the town to try to finger out how to stop the snakes from killing people they get trapped in the end but they get saved and during the movie they fall in love...
