Supergirl has created an app with special powers but needs to test it. She calls Rose, activates the app and Rose is now frozen. Supergirl binds her, leaving her hogtied with rope and gagged. The trap is set to capture UltraGirl and it works as planned. UltraGirl comes to Rose's rescue but is frozen by Supergirl's app. She ties UltraGirl's legs then her arms behind her back before tying them both together. But Supergirl has a more devious plan. She has another function on her app that will emit a high high-pitched sound that will melt their brains. As she walks away, they struggle and struggle and finally break free. They both attack Supergirl, tie her legs with rope and tie her arms behind her back. UltraGirl plans to use Supergirl's app against her, setting it to emit the sound that will melt Supergirl's brain as they walk out of the room. What will happen to Supergirl?
