Combining magical realism and post-colonial satire, Imperial Blue is a contemporary take on the "white man in Africa" narrative, set mainly in western Uganda.

American smuggler Hugo Winter travels to Uganda to find the source of Bulu, a mysterious shamanic drug with prophetic powers.

While buying kilos of hashish in India, American smuggler Hugo Winter is offered a sample of a rare herb from Uganda called Bulu, which is said to bestow the powers of prophecy.

Meanwhile, Angela's eagerness to close a deal with Hugo becomes increasingly appealing when he receives news from London that his family has been attacked and he must return immediately.

Hugo, injured and lost in the forest, takes a very large amount of Bulu in an attempt to see his way out of the situation.

Imperial Blue has received largely positive reviews, praising its direction, cinematography, locations, acting and original narrative.

"[4] Ellen E Jones of The Guardian praised the "impressive locations" and singled out the performances of Esteri Tebandeke and Rehema Nanfuka as "excellent", but was critical of the decision to focus on a white male lead.

Most of the crew of Imperial Blue, at all levels of seniority, were teachers, graduates and students of Kampala Film School, which producer-writer David Cecil founded in 2011 and at which director Dan Moss lectured in 2012–16.

Imperial Blue was, in this sense, the culmination of the two British film-makers' engagement with the Ugandan film industry, and their attempts to build capacity therein through education and co-production.
