A Saiyan named Taurus has invaded Earth in order to plant a tree that will both destroy the planet and give Taurus strength a hundred-fold. Goku and the Z fighters aren't going to let this happen and duke it out with Taurus's group for the sake of the Earth.

This movie has more alternate storytelling than the previous movie did. As the movie went, it has little connection to the anime series than the whole meeting Icarus part in the movie, who only appears during the Garlic Jr. Saga.

That and the introduction of Taurus who only appeared in this movie and was never mentioned during the first 3 seasons of the anime. As he and his minions wear the same uniform for Frieza, but they never mentioned their leader even though it's obvious who they work for.

So in short, the Dragon Ball fans will enjoy this title for an alternate storyline movie.
