Sumiko Dreams and Lucy Purr are popular superheroines. A nerdy chemist has invented a new powerful formula. Sumiko and Lucy are sent to check it out. It is all a setup, though, and peril ensues. The superheroines enter the room with the understanding they will be testing out the formula. The chemist hands them the liquid. They each take a sip and suddenly begin to feel lightheaded. Trying to shake it off, the chemist tells them it’s a “strong-sedtive”, to which a confused Sumiko responds with, “I thought it was a serum…?” Within moments, Sumiko Dreams collapses on the couch behind her, and Lucy Purr follows immediately afterwards. The chemist is pleased at the effectiveness of the formula. When the heroines wake up, groggy and disoriented, they try to make sense of what’s happened. They briefly discuss before hearing the sound of a gas dissipating through the air. Lucy Purr sniffs the air, her eyes rolling back. Before she can get the words out, Lucy slumps onto the couch. Sumiko’s eyes get heavy and she falls next to Lucy Purr. This next time, Sumiko Dreams and Lucy Purr come to and confront the chemist standing before them. They tell the villainess that she has made a big mistake and will be brought to justice. At this point, the chemist hits them both in the face with a spray. Sumiko and Lucy protest weakly, then begin to sway. Ultimately, this puts superheroines Sumiko Dreams and Lucy Purr into a trance. The chemist uses this opportunity for a little mind control, convincing the non-resistant heroines to strip naked. Once down to bra and panties, Sumiko snaps out of the trance and snaps Lucy out too. The angry heroines approach the chemist. But, no sooner do they do this than they are each hit in the neck. Tranquilizer darts! Sumiko Dreams and Lucy Purr go down while the evil chemist revels in her success.
