Nels is showing off in front of Harriet with a sword when he accidently cuts off the head of an expensive store dummy. Seeing this through the window, Laura is convinced that Mr.Oleson has beheaded his wife! The trouble is, she can't get anybody to believe her but Nellie and Willie certainly have fun stringing her along as THEY are fully aware that their mother is temporarily out of town and go out of their way to encourage Laura's belief that their passive, gentle father has committed murder!
Nels was funny her in several places, as was Harriet, but there was something wrong with the script for me and that's why I didn't enjoy it as much as I would have liked. Good work from all the youngsters, though.
