Derek Hough joins Bear on a whirlwind adventure across the mountains of Bulgaria. Dropped amidst snow-capped peaks, Derek and Bear must ascend a jagged mountain ridge, make a steep rappel with Derek's cell phone as their only safety, and swim a freez... (more)ing lake to reach their destination. But a surprise, death-defying final challenge will test Derek like nothing before. Along the way, Derek reveals his struggles with being bullied as a child, his devotion to his craft, and teaches Bear some much-needed dance moves.
