The documentary film covers Dr Fred Urquhart's interest in monarch butterflies, with perspectives of Urquhart as a child wondering where the butterflies went, his years of research and study into their life and migration, to his time decades-later as a senior scientist looking back at his investigations and discoveries about the insect's life pattern.
