Cap reminisces about a past confrontation in World War II. The Ultimates and 20,000 S.H.I.E.L.D. troops are on their way to the Chitauri base in Micronesia. However, it becomes clear that the Chitauri are one step ahead... infiltrating the Triskelion and laying a lethal trap for the Ultimates task force.
