The Neo Zeon remnant group, "The Sleeves", travels to Side 4's Industrial 7 colony, so that its captain, Zinnerman, can meet with the Vist Foundation leader, Cardeas Vist, to receive a "key" to something known as "LaPlace's Box", which is said to be capable of either restoring the future, or destroying the world. Audrey Burns seeks to meet Vist first and convince him not to turn over LaPlace's Box, believing the Sleeves will use it to start another war.
