 The sisters need to call in accident-prone Brother Paul back to the convent to do some bookkeeping work. The sisters do everything in their power to keep Brother Paul from doing harm to himself, to them or to the convent. Brother Paul is not accident-prone like he was during his last visit. On the other hand, Sister Bertrille is causing a lot of accidents and a lot of accidents are happening to Sister Bertrille by others in their attempts to avoid accidents to/from Brother Paul. The nature of the bookkeeping work is primarily in regard to Carlos  donations since he is being audited. When Mr. O Reilly from the IRS needs to change his appointment with Carlos, Carlos uses the opportunity of his own accountant s absence at that time to use the services of "pious" Brother Paul for the audit. Brother Paul s first and only accident at the convent happens when he sees Sister Bertrille fly and in turns drops all Carlos  tax receipts, which go flying into the wind. Carlos and Brother Paul have to hold off Mr. O Reilly while Sister Bertrille goes flying off for receipt after receipt. By the time Mr. O Reilly completes his audit, Sister Bertrille has not found all the receipts and Mr. O Reilly does not allow the total amounts Carlos has requested for deductions. It isn t until Sister Bertrille flies after Mr. O Reilly with the remainder of the receipts that he changes his mind to allow whatever Carlos, Brother Paul and especially Sister Bertrille want.
