Barry, Clark, Batman, Bruce, Lara, Terry, and Jessie all retreat to Barry's universe in order to stop Rverse Flash once and for all. Barry want's to get help from his world's Justice League and Wally, but Keaton's Batman says they can handle it, while Gyllanhaal's Batman says they need the help. However things get even more crazy as villains from the multiverse try to kill Barry. Most from none other than the Arrowverse. And I'm sure you all know what happens here.
