Babysitting Without a Net (2006)

Laura-Ann, a soon-to-be school teacher who is stuck in a Victorian-era time warp that makes her behave like a strict, fussy disciplinarian and dress like a scary grandmother from the 1850's, takes on the responsibility of babysitting over the summer, two 15-year-old juveniles named Amy and Louise. Laura-Ann sets out to tame and refine the two girls, and a sumptuously artistic escapade ensues, a battle of wits and wills, and only the strong survive.
