The Red Ribbon Army, an evil organization that was once destroyed by Goku in the past, has been reformed by a group of people who have created new and mightier Androids, Gamma 1 and Gamma 2, and seek vengeance against Goku and his family.
When a movie has you begging for it to end not even half way through it's pure crap. We've all seen this movie and this characters millions of times, nothing new in it. Don't waste your time.
Like the great film, it's made with a great deal of visible affection both in front of and behind the camera.
