 Lucy competes with her friend Carolyn Appleby over invitations and scheduling for Little Ricky s birthday party. When her husband Ricky mentions that Superman star George Reeves is in town, Lucy tries to get Reeves to come to Little Ricky s party, sure that this will make it a much bigger draw than the one Carolyn is hosting. Ricky tries, but Reeves can t make the party. So Lucy disguises herself as Superman, but gets herself into great peril. Fortunately the "real" Superman does show up to save the day.
