This summer… the two greatest detectives in history must put their heads together to ensure the survival of the entire universe. While Batman (Christian Bale) is attempting to rescue Dr. House (Hugh Laurie) and Alfred (Michael Caine) who were abducted during a checkup by the Green Goblin (Willem Dafoe), Loki (Tom Hiddleston) opens a gateway to London in 1899, sending everyone crashing into 221B, Baker Street, home of the intrepid detective Sherlock Holmes (Robert Downey Jr.). With the help of Sherlock’s brother Mycroft (Stephen Fry), this motley crew embarks on an epic adventure to track down Loki and the Goblin and find a way for Batman, House and Alfred to return to their time, only to discover that Loki and the Goblin are but a small part of a sinister plot that threatens to unravel the time-space continuum, masterminded by none other than Nicholas Cage (Samuel L. Jackson). Also starring Scarlet Johansson, Kate Beckinsale and Zooey Deschanel, with narration by Morgan Freeman.
