 Sister Bertrille finds Uncle Reggie, who is still the prime suspect in the casino robbery. Unfortunately for Uncle Reggie, Captain Fomento also finds him. Sister Bertrille however convinces Carlos and Captain Fomento of Uncle Reggie s possible innocence, and devises a plan to flush out the real thieves: report that Uncle Reggie has been caught and charged with the theft, so that the real thieves will let their guards  down. It works as Bruce and Faye, still under cover at the convent as Sister Mary Grace, decide that it is time to leave San Tanco. The sisters unwittingly leak to thief Faye that the story of Uncle Reggie s guilt is just a ploy. Faye as Sister Mary Grace still meets up with Bruce at the airport, but Sister Bertrille sees the two together in a compromising position and sees Bruce take off with Sister Mary Grace s luggage, and suspects they may be the possible crooks. With information from Uncle Reggie and Carlos, Sister Bertrille pieces the whole thing together. She follows Sister Mary Grace/Faye to Bruce s hideout and manages to steal their car, leaving the two thieves stranded - they are forced to walk a mile to their departure point of the harbor. Sister Bertrille alerts Captain Fomento and Carlos, who rush to the harbor to apprehend the thieves. But Sister Bertrille beats them to the harbor and confronts the crooks, who have her at gunpoint. As Bruce trips, he accidentally pulls the trigger and the gun goes off. Next they know, Bruce and Faye sees Sister Bertrille up in the air, thinking that they killed her and what they see is her angel. Just then, Captain Fomento and Carlos arrive on the scene and arrest the crooks.
