People have always dreamed of finding a new planet, which will be inhabited with life forms that we can communicate with. But, what happens when they do? Captain Charles T. Baker is one of the main characters in this animated movie that deals with this idea. The plot revolves mostly around him and his discovery of something that humans call Planet 51. As he gets there, hoping to be the first man to walk the surface of a new planet, Captain Charles T. Baker (voiced by Dwayne Johnson) finds out that not only he isn't the first one, but the life on that planet has evolved that much, that the inhabitants are living the life of Americans from the 50s. Of course, soon after his landing, his space ship breaks down and there are special units surrounding the ship. Not long after that, Charles gets to meet an unusual alien kid, who is spending the most of his free hours in the local planetarium and library, and is unlike the others, pretty educated and knows that humans won't eat them. So, he is the one who tries to help Charles get back to Earth safe and sound, without getting caught or arrested.
