The Justice League finds itself in the middle of a diabolical "reality show" along the Las Vegas strip. It seems that the Joker has planted time bombs all up and down the main drag of Sin City, and has given the JLers only a few hours to deactivate the explosives. Complicating matters is the interference of The Joker's newest henchpersons, the "Royal Flush Gang": Ace, King, Queen, Jack and Ten (their voices ironically supplied by cast members of
Justice League's "sister" animated series
Teen Titans). ~ All Movie Guide
