Liv and Maddie are identical twins who couldn’t be more different. Liv’s got fame and Maddie’s got game! Maddie ditches her dad at a basketball tournament to play with Joey’s new fitness trainer, Liv gets jealous when Maddie and Karen take part in a mother-daughter weekend of pioneer living, and the girls pretend to be Willow’s secret admirer so that Willow will stop crushing on Joey. They’re sisters by chance, but friends by choice – and now that they’re living under the same roof, anything can happen!

It may be chaos under this roof, but the Rooneys are one big happy family. Maddie tries to find another hobby because her injury prevents her from playing basketball, Joey thinks it’s a prank when a cute cheerleader asks him to the dance, and Parker builds a robot dog to prove he can take care of a real one. And what will Liv do when she discovers her big movie premiere is the same day as the annual Cheddar-Brat Fest! They may be twins but Liv and Maddie are one of a kind. In this fast-paced world, life certainly doesn’t slow down for the Rooneys! Liv runs into a cute boy from her past but things get complicated when she and Andie both realize they have feelings for him. Meanwhile, Joey goes to extremes in order to impress a girl and Parker’s inventions spell out trouble for Karen. And with all the ups and downs in their relationship, can Maddie and Diggie stay together or will they go their separate ways? They may not have it all together, but together the Rooneys have it all!

When the Rooneys can’t go to Hollywood, Hollywood comes to them! The new show Voltage begins shooting in Stevens Point with Liv as its star and a new boy in town. Meanwhile, everyone’s wondering if Maddie got her chance to tell Diggie how she felt before he left for Australia! And, Joey tries to seem cooler by getting rid of his cat shirts while Parker tries to invent a new vegetable. Liv stars in a new TV show, Voltage, with a new co-star, Josh Willcox, who is also Maddie's new boyfriend. No matter what is thrown their way, Liv and Maddie know they can handle it all as long as they’ve got each other!
