We Should Worry (1918)

Little Jane and Katherine approve of the romance of Miss Ashton, their rich and beautiful aunt, with Jack Fenton, but when she becomes distracted by the debonair Percival Gilpatrick, whom the children detest, they decide to intervene. After the children interrupt his attempted marriage proposals several times, Percival, actually a crook, orders his accomplices, Mike and Bill, to keep the girls occupied. Annoyed that Percival would rather court Miss Ashton than rob the bank, however, Mike and Bill decide to kidnap the children and hold them for ransom. Imprisoned in a cellar, Jane and Katherine torment the two men with their pranks until the crooks willingly release them, but Percival stages a rescue that, much to the girls' dismay, impresses Miss Ashton. Later Percival and his men rob the bank, but the youngsters aid the police in catching them. Miss Ashton then happily agrees to marry Jack.
