Dizzying heights & tough courses - who will master the action week?

At the casting for the new CALZEDONIA campaign, the models show off their best side. In keeping with the "action" theme, which is what this episode is all about, the next day's "Balance Beam" shoot takes them to the skies, as photographer Max Montgomery photographs the models on a narrow beam. The Elimination Walk takes them through an obstacle course, where they have to impress Heidi Klum, designer Kevin Germanier, and supermodel Coco Rocha.
