2013 год. The Crazy Cat Crew love to dance – they groove and they bop, they move and they hop, all night long. Then, one night, Arthur slinks off and discovers something really special; a pair of ballet shoes. He immediately puts them on and goes back to show the gang his new style of dancing. But the other cats don't like ballet and laugh Arthur out of town … only to realize that all dancing is cool and that they really miss their friend.
