Mother Superior assigns Sr. Bertrille to help accident-prone Bro. Paul put the convent library in order. Bro. Paul wistfully tells Sr. Bertrille he had hoped to spend his life at the Vatican Library but things hadn't worked out. He sorts out the books to be discarded into a separate pile. Then he puts the shelves in the sun, with his magnifying glass on top. When he pulls out a big nail, Bro. Paul finds some valuable old parchments in the wall. For safe keeping, he puts them in an encyclopedia, which finds its way onto the discard pile. The magnifying glass starts a fire, burning up the bookshelves. Sr. Bertrille swaps the discarded books for new shelves with Swapping Salvador. Bro. Paul later remembers where he put the old parchments. Sr. Bertrille panics when Sr. Jacqueline informs her Salvador has planned to grind the old books into pulp. She flies to Salvador's yard just in time to save the parchments. Mother Superior is impressed by the beautiful job Bro. Paul and Sr. Bertrille did on the library. Bro. Paul is assigned to work at the Vatican Library as a reward for recovering the lost scrolls of San Tanco. After he leaves, Sr. Bertrille has a series of accidents. Sitting in the rubble of Mother Superior's desk, Sr. Bertrille wonders if Bro. Paul's talent for accidents is catching. watch
