A couple of years after the previous film, Mr. Freeze has escaped Arkham Asylum along with Two-Face and Firefly, and all three start wrecking havoc on Gotham City, together. However, in the time between films, Jason Todd was killed by the Joker. It's because of this that Batman has become more brutal as a vigilante. A young man named Tim Drake takes notice of this and decides to train himself to become the next Robin and help Batman at any cost.
