When you're as small as an ant, the world is big - and adventure is bigger! That's what young Lucas learns after he aims his water pistol at some hapless ants. They retaliate with a secret potion that shrinks "the Destroyer" to their size... and turns an anthill into a mountain of thrills, action and laughs! Julia Roberts, Nicolas Cage, Meryl Streep and Paul Giamatti head the cast of this rollicking, warm-hearted family treat.
