Old Lund is determined to make his granddaughter Lise/Liz a great dancer. He teaches dance classes in their attic home, accompanied by their neighbours, Pat and Patachon, playing the flute and violin. Joy fills the household when Lise secures an engagement at the Grand Theatre, but acquiring the expensive costumes she needs becomes a financial burden. Pat and Patachon secretly decide to raise the necessary funds by selling Patachon’s skeleton to the Zoological Museum. (Stumfilm.dk)
