M1, T15: Sister Bertrille searches for rocks for her nature study class. To avoid her, Bill Watkins dodges into a deserted mine. When Sister Bertrille enters, he slugs her. Using judo, she slams him against the wall, dislodging a shower of rocks which blocks the passage. Bill feels that being buried alive with a nun, even a novice, is just more of his bad luck. Deep in the mine, Sister Bertrille finds an opening high above. They try to throw rocks through it but the first one bounces back on Bill's head. He produces some bourbon for first aid but Sister Bertrille pours it over his head to prevent infection. They try to rig up a catapult and a ladder but fail. Then Sister Bertrille discovers Bill has escaped from a detention camp, but makes no comment. Bill admits he wanted to be a doctor but was cheated out of the money he saved by his alcoholic father. To make it up, he agreed to do some smuggling but was caught. Bill thinks he's dealing with a kook when Sister Bertrille says she could fly out. To create an updraft, she wants to build a fire but Bill stops her. Sister Bertrille challenges his faith and even tries judo. Resigned, Bill hands her a book of matches. After making him promise not to tell anyone, Sister Bertrille flies out of the mine, and rescues Bill with a ladder of tires from the station wagon. Awed by his experience, Bill feels his luck finally has changed.
