The 8th Unit is given unofficial R&R on the neutral island of Bellhals. Jamie has a coupon to a luxurious spa on the island and plans to visit, but is called by her boss at the last minute to update Argevollen's OS. The rest of the women go to the spa, while the men hang out at a local bar.

The episode opens with a flashback of Samonji meeting Tokimune's sister in the same sunflower field sometime in the past. In the present, Samonji orders everyone back to the command post. He later receives confirmation from his friend Quasimodo that the reason his supplies were late was due to an Ingelmian sympathizer using the same ship to transfer some unnamed heavy equipment.

Suzushiro tells Tokimune about the events behind his sister's death at Argent Point. At the time, Samonji was a Second Lieutenant and the leader of the base's security force which included herself and Quasimodo. Reika was a Sub-Lieutenant and the pilot for a new Trail Krieger that could use its pilot's brain to control unmanned mechs in the field.

The Kitazamahara base is wiped out in the battle between the Argevollen and the new enemy unit. The 8th retreats to Pudder base to recover and regroup. They chart a course through an abandoned industrial city, and bait the "Ghost" into attacking, but in the ensuing battle Tokimune loses control.

Cayenne rebels against the Arandas military, and Captain Samonji sides with him. The 8th Unit goes to stop Samonji, but Argevollen is captured instead.
