What Happens in Old Bones of the River: Full Plot Summary

The whole story of Old Bones of the River (1938) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

In colonial Africa, Professor Tibbetts [Will Hay] leads the Teaching & Welfare Institution for the Reformation of Pagans (T.W.I.R.P.), a program dedicated to spreading education among the native populations.

The Professor is the uncle of Lt. Tibbetts, known as "Bones," and is affectionately called Old Bones.

As he arrives, still trying to learn the native language via recordings, Prince M'Bapi, half-brother of Bosambo, chief of the Ochori, tricks him into sneaking a gin still into the country.

The steamer that brings him takes Commissioner Sanders on leave, with Captain Hamilton taking over his duties.

Later, Tibbetts makes his way to Kombooli High, where his students wear Eton collars alongside their native garb. He dons a mortarboard but wears safari shorts under his gown owing to the heat.

When Hamilton falls ill with malaria, Tibbetts is forced to take over his duties, which include collecting the taxes. Traveling upriver by canoe, he discovers Sanders' paddlesteamer Zaire, run by Moore Marriott as Jerry Harbottle and Graham Moffatt as Albert Brown.

M'Bapi leads a revolt against Bosambo, and the three protagonists rescue a baby from death by sacrifice.

Old Bones of the River Plot Explained: Your Questions Answered

The questions people ask most about Old Bones of the River (1938): what happens in the confusing scenes, why the characters do what they do, the twists, hidden details and what the ending means. Each answer contains spoilers.

Q1

Why did Prince M'Bapi trick Professor Tibbetts into smuggling a gin still?

Prince M'Bapi, who is the half-brother of Bosambo (chief of the Ochori), exploited Professor Tibbetts' naivety and inexperience with local customs. Tibbetts was still trying to learn the native language through recordings and was unfamiliar with the political landscape. M'Bapi used this to his advantage, getting the professor to unknowingly bring the gin still into the country for his own purposes.

Q2

How did Professor Tibbetts end up collecting taxes?

Captain Hamilton, who had taken over Commissioner Sanders' duties when Sanders went on leave, fell ill with malaria. This left his administrative duties unattended, so Tibbetts was forced to step in and take over, which included the task of collecting taxes from the native populations in the region.

Foreshadowing: The earlier scene where Tibbetts struggles with the native language hints at his unpreparedness for administrative work.

Q10

Why did Professor Tibbetts wear safari shorts under his academic gown?
