In "White Cube," Renzo Martens examines the exploitation of African plantation workers by the Western art world. By founding an art cooperative in the Congo, he enables the workers to produce works of art for the Western market and profit from the proceeds. These are exhibited and sold in museums around the world, which means capital flows back to the plantation.

A central element of the project is the construction of a museum, a so-called white cube, on a former Unilever plantation. This museum is intended to symbolically direct the flow of capital back to the plantation and provide the workers with a platform. Sculptures are digitized and cast in chocolate to make colonial connections visible.

The film asks critical questions about the relationship between art and capitalism and shows the harsh working conditions as well as opportunities for social and economic change through art. "White Cube" appeals to museums in the global north to decolonize their collections and actively contribute to improving living conditions.
