小丑所率领的敌人们突然袭击了日本！他们的目的是，想要夺取鹰爪团的秘密武器，然后用它进行大肆破坏。事先察觉到了危机的正义联盟聚集到了东京，跟鹰爪团的人进行了汇合，但其中却没有蝙蝠侠的身影。没想到蝙蝠侠居然退出了正义联盟！然而，电影鹰爪团最大的弱点是预算不足。聘请了数量庞大的角色们需要庞大的使用费，以及高质量的动画画面创作。简单来说正义联盟脱离了大富豪蝙蝠侠的资金援助，就没有办法展现出令人满意的打斗戏，连一些小龙套都打不赢！鹰爪团和正义联盟，到底能不能把宅在家里的蝙蝠侠叫回来呢？以及，他们究竟能不能粉碎小丑的野心呢！？

Joker has come to Japan to steal the Eagle Talon Society's secret weapons in his continued scheme for pure chaos. However, the Justice League is on his trail, but there's something off with Batman. Now, it's up to Eagle Talon to go find out what's wrong with Batman, and that means going back in time to Bruce Wayne's most traumatic experience, the murder of his parents. If that wasn't enough to worry about, the Eagle Talon Society also have to keep their eyes on their production budget, especially with most of that money going towards the licensing fee for DC's popular characters. Will the Eagle Talon Society and the Justice League be able to stop the Joker before their budget dries up, and they're reduced to simple stick figures!?
