Rurouni Kenshin Prequel Movie(s) ?

So I heard there was a prequel movie. I then googled it and a lot of people said there are four movies. One is Samurai X: Trust and Betrayal, one is Samurai X : Reflection, one is Samurai X : The Motion Picture, but I can't find the fourth and I don't know what order to watch them in. Can anyone help me out?
