Down Will Come Baby was a 1999 TV movie made for CBS starring Meredith Baxter and Evan Rachel Wood. A bulk of the action centers around a creepy neighbor who stalks, kidnaps and attempts to brainwash 12-year-old Robin Garr (Wood).
The stalker, who goes by Dorothy but is really named Gretchen, befriends Robin because she is the last person to have seen her daughter Amelia alive. Robin and Amelia meet toward the beginning of the movie at Camp Clear Lake, where Amelia drowned during an evening swim with Robin, who egged her on to race her through deep water to the dock.
The above video captures the scenes in the beginning of the movie at Camp Clear Lake, where we get our first glimpses of how twisted stalker Dorothy is through Robin’s interactions with the socially awkward Amelia.
