The true story of inexperienced District Officer Cadet Arthur Grimble (Denholm Elliott) who arrives with his bride Olivia (Susan Stephen) on a remote Pacific island to work in the Colonial Service. He finds it hard to meet the approval of his superior, the Resident Commissioner (Michael Hordern), who had been expecting a more experienced man. The harder Grimble tries to please him, the more things seem to go awry, and he soon finds himself banished to a smaller neighbouring island. Olivia though is not as easily discouraged as her husband by the situation, and lends her support in a way that eventually meets with the approval of the island people.
