The short starts off with Bart recapping Maggie in Peril: Chapter One which abruptly ended. The short continues with Maggie plunging down the waterfall and emerging out fine from it. The skateboard goes up a rock like a ramp, having her in the air and landing on a small cliff. She heads through a circus and floats through the air with a bunch of balloons. As Marge and Homer are driving home, Mom squints on a view of Maggie from the car although she cannot recognize her. Maggie then lets go of a balloon one at a time to levitate lower before letting go the remaining balloons and rolling down the house's roof and going back down to her crib by a tree's branch and the skateboard landing back by Bart and Lisa. The parents just then arrive as everyone goes to check on Maggie. When Bart and Lisa see the skateboard back, they are both relieved. The short ends when Maggie takes a sigh of relief.
