I am looking for a movie title, that an ice-creame seller has to save a cemical bomb in its fridge, cause if it gets warm it explodes and they finally end up trapped in a tunel somewhere in Ukraina I think. I hope somebody will give me a clue about movie title or any actor name. Thank you.

Chill Factor (1999) (http://www.imdb.com/title/tt0163579/)

Thanks a lot bro.

You're welcome.
