After the great success of The LEGO Movie, Batman (in English by Will Arnett) experiences his first solo adventure. This time, the question is whether the gloomy criminal can really be happy. Despite his immeasurable fortune, the faithful butler Alfred (Ralph Fiennes) and a bath cave full of high-tech gadgets, Bruce Wayne prefers to spend his sleepless nights alone. This changes when he accidentally adopts a small boy on a gala. Dick Grayson aka Robin (Michael Cera) becomes a loyal, if somewhat annoying, companion. When Batman is quiet, meditative and deadly, Strahlemann Robin becomes all the happier and more enthusiastic. That it comes between Zoff and Zoff is actually pre-programmed. Despite this, the Superteam are still gathering together, as they have a great mission to protect Gotham City from evil. When the archduke Joker (Zach Galifianakis) makes the city unsafe, the two really have to work together. Joker wants to play, and with his mad strokes finally be respected by Batman.
