Movie starts in the jungle when terrorists take control of a deadly virus and then threaten to release it. After that a Special Forces team (Deltaforce) begins to hunt the terrorists down and there is a lot of pointless gunfights until the end on the movie - which ends happily for the world (surprise, surprise). From time to time it's difficult to understand what is going on. One of the stars - Ernie Hudson makes a lot better appearance in prison drama series "Oz" than in the "OP Deltaforce". Other "stars" where unknown for me.
But if you like plain action and don't care much about the story, then this movie is made just for you… some of the action scenes are quite exciting.
If you don't like pointless action films, then you should look for something else:)
