This documentary explores Dr. Fred Urquhart’s fascination with monarch butterflies, beginning with his childhood curiosity about their mysterious destinations. It follows his extensive research and study of their lifecycle and migration, culminating in his reflections as an experienced scientist on his groundbreaking findings about these insects’ migratory patterns.
