As the squad prepares for the D-Day invasion of the bug home planet of Klendathu, Dizzy receives an official notice from S.I.C.O.N. that her brother, Eddie is presumed dead. The news deeply effects the normally gungho Trooper, causing her to become skittish in battle. Unfortunately, the orders come down for the invasion to begin. Dizzy's hesitation concerns Rico (who has just been promoted to Sergeant) and he must determine if she is still fit to be a part of the Roughnecks. Eventually inspired by the fierce determination and never-say-die attitude of a Zulu Squad Trooper, Dizzy regains her confidence in time to save the Roughnecks and help them achieve their mission.
