An army officer is caught outside during atom bomb test for some reason this causes him to grow. He becomes a giant that eats a lot and is in pain due to heart problems. The scientist explains that the heart is made of one cell. Now that is what I call really bad biology was the director on serious illegal drugs. This isn't the films only bad biology moment there is the scene where they shrink an elephant with the use of an injection. The plot of this movie is so weak and the ending is horrible. Bad attempt at a suspenseful drama with some bad I mean bad biology. Watch the Mystery Science Theatre 3000 version of this movie. Believe me folks I wouldn't watch this movie on its own. Heart made of one cell hehehehehe.
