Robotech S02E05 - Half Moon

Dana and Bowie stumble into an excavation operation by the Robotech Masters in the remains of what was once New Macross City, centered on the earthen mounds that hold the remains of the SDF-1, SDF-2 and Khyron's battlecruiser. Bowie is captured. Enraged by her superiors' refusal to authorize a rescue operation, Dana fakes a late-night training exercise to launch the mission herself.
