Pint-sized troublemaker Dennis The Menace hits the high seas in this made-for-TV animated feature. Mr. Wilson (voice of Tom Arnold) and his wife Martha (voice of Marilyn Lightstone) decide to take an ocean cruise to get away from it all, but much to Mr. Wilson's chagrin, he discovers one thorn in his side will be following him -- Henry and Alice Mitchell (voices of Maurice LaMarche and Marilyn Lightstone) are also taking the cruise, and have brought along their rambunctious son Dennis (voice of Brennan Thicke). When he's not busy needling Mr. Wilson, Dennis and his friends discover an exotic foreign princess is also on board, but a pair of thieves are following her, hoping to use hypnosis to steal her valuable jewels. Can the kids convince the grown ups that the bad guys are after the princess before it's too late?
