Marge notices that Homer's vision is slipping, so she takes him to the mall for laser surgery. While they wait for him, Marge and Lisa see a romantic movie with a tango dancing theme. With that inspiration, Lisa wants to take dance lessons. She starts to learn tap from a former actress. Bart and Milhouse go away to camp, but end up staying at the mall instead. They damage it severely, and Chief Wiggum searches the mall for a giant rat. Lisa struggles in her quest to learn to dance; she finds that she has little to no talent. Bart and Milhouse try to outwit a lion at the mall. Lisa's teacher makes her the curtain puller in the big recital. Professor John Frink sees her troubles and gives her a pair of tap shoes that will make even her look good. At the recital, she dances out onto the stage involuntarily, ruins the production and comes to the realization that she is no dancer.
