Sue Storm (as Invisible Woman) lurks around The Puppet Master's lair, trying to find Ben and Alicia. The Puppet Master senses Sue, and releases sleeping gas into the entire room. Sue tries to stay awake, but the gas overcomes her. As she passes out, her invisibility goes away. A classic scene that is based on a story from the comics.
