April Showers bring...Mr Freeze? When the cold-hearted super-villain is granted his freedom from Arkham Asylum, he is welcomed back to Gotham, but the city's warm embrace will turn cold if Batman can't stop him. Then, on Cinco de Mayo, Damian Wayne, Batman's son, leads his friends into battle with the seedy underworld of street racing, cage wrestling, and back-alley taco-eating competitions!
