I remember watching this when I was a little kid, maybe four or five, and I LOVED it! It was one of the few episodes of the series released on VHS and I made my parents buy it for me along with the Titan of Terror VHS which had Sliced Ice's other KO and capture scene. Here, Kim Sakai (Sliced Ice) disguises herself as her scientist friend and does some sleuthing. But in true Nancy Drew fashion, she gets knocked out and taken back to the villain's hidden base. There, she's able to get free and transform into Sliced Ice only to get captured once more. The scene with her lying unconscious on the ground is actually a traveling shot but I was able to cobble together multiple shots to get a complete view.
