Members of the Neo-Zeon group "The Sleeves" travel to Side 4's Industrial 7 colony to rendezvous with Cardeas Vist of the Vist Foundation and retrieve a mysterious item known as "Laplace's Box." Little do they know that Zeon Princess Mineva Lao Zabi has stowed away aboard the ship with the intent of meeting Vist on her own accord. Meanwhile, Anaheim Electronics Academy student Banagher Links detects Mineva's presence and commandeers a mobile worker to rescue her from falling through the colony's sky.
