Banished to an alternate universe where humanity is enslaved and superhumans are almost extinct, Kevin Jason (Bolt) must race against time to return to his own universe in time to stop the most dangerous supervillain he's faced yet. Allying with a ragtag group of rebels, Kevin must break into a heavily-fortified castle to gain access to the technology that will take him home, a seemingly insurmountable task even for a superhero of his powers and talents. With the fates of two universes on his shoulders, Kevin cannot afford to fail.
