I tried to do a spoilers code around this, but it didn’t work, so be casual viewers be warned…
SPOILERS:
Bunny is found alive and well at the end of the movie. It was the brother who kidnapped her, jealous that she was taking all of the sister’s attention away from him. He goes completely looney, and Tuesday Weld’s character distracts him by playing children’s games (including hide and seek) to get herself and Bunny away from him.
<covering eyes to avoid the spoiler above> Are there any plans yet to release this on DVD or at least air it? I don’t think it’s been aired (in the US- heard it was aired in the UK in the 80s) within my lifetime, and I’ve been hoping for three years to get to see it after hearing the plot.
