When Angelina learns the Mousnikov Ballet is holding auditions for their next show, she does whatever she can to try out; however, her young joints and muscles can’t hold her up en Pointe. She doesn’t let anything stop her as she continues to practice until she can no longer stand. Simultaneously, Marco is trying a new String Bass, but accidentally practices on a full-sized instrument instead of one that fits his size. They both learn that despite their efforts, they’ll have to wait to grow up before reaching new heights in their crafts.
