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. Along the way, she is rescued by sixteen year old student Banagher Links, who agrees to take her to meet Vist. Meanwhile, a battle breaks out between the Federation's Londo Bell task force and the Sleeves. As the collateral damage rises, the colony is evacuated. Amidst the chaos, Banagher discovers the fatally wounded Cardeas Vist in the cockpit of the Unicorn Gundam. Before his death, Vist entrusts the Gundam to Banagher, who realizes that Vist was his father. Banagher then launches in the Unicorn Gundam and confronts the Sleeves' elite pilot Marida Cruz, who is piloting the Kshatriya.
