What Is Sleeping Sickness About?
The premise of Sleeping Sickness in 312 words, with nothing given away. The full story follows below.
In the humid heart of Cameroon, a modest clinic quietly combats a disease most of the world has forgotten. Ebbo Velten has devoted himself to the sleeping‑sickness programme, finding purpose in the slow, steady rhythm of field work while the surrounding landscape hums with the sounds of distant cities and untamed rivers. The film paints the region with a gentle, almost lyrical realism, letting the heat, the mosquito‑laden evenings, and the soft murmur of local conversations shape an atmosphere that feels both intimate and expansive.
At home, Vera navigates the expatriate enclave of Yaoundé, a community that offers polite smiles but little comfort. Her marriage to Ebbo feels stretched across continents, especially as their fourteen‑year‑old daughter, Helen, spends most of her school years in a German boarding school, returning only for brief, bittersweet visits. Vera’s sense of displacement is amplified by the distance between her personal aspirations and the expectations that linger in the shadows of the aid world, creating a quiet tension that underlies everyday interactions.
Years pass, and the project’s future hangs in balance. When a French‑Congolese doctor arrives to evaluate a new development initiative, the quiet routine is subtly disturbed. Alex Nzila steps onto the scene with the professional detachment of a World Health Organization inspector, yet his presence triggers a ripple of questions about commitment, legacy, and the cost of staying versus leaving. The encounter between Alex and the withdrawn Ebbo becomes a focal point, hinting at unspoken histories and the fragile bonds that tie people to a place that is both a refuge and a crucible.
The tone of the film is contemplative, blending moments of gentle humor with an undercurrent of melancholy. It asks what it means to belong to a cause that is half‑finished, and how love, responsibility, and the pull of distant homelands can reshape a life lived on the edge of the unknown.

Spoilers ahead
Ebbo Velten, Pierre Bokma, works in Cameroon on a sleeping sickness aid project and lives with his wife, Vera, Jenny Schily. Their daughter, Helen Velten, Maria Elise Miller, usually attends a boarding school in Wetzlar, Germany, but visits them. There are few patients, though European aid remains generous, and Velten’s family plans to move back to Europe while he stays behind to continue the work.
Three years later, World Health Organization inspector Alex Nzila, Jean-Christophe Folly, arrives to assess the programme. Before he reaches the clinic there is friction with local people who fear over-paying or being robbed. On arrival at the clinic Velten cannot be found. A woman in the clinic goes into obstructed labour requiring a Caesarean section. Velten arrives just in time to perform the operation and deliver the baby. The baby girl is his, from his relationship with the mother. Soon the woman’s relatives arrive to celebrate the birth. Velten brusquely refuses to give the woman’s brother money when his “father-in-law” asks him to help, creating tension with the family.
Velten then shows the inspector the sleeping sickness clinics; no cases have been reported. He also takes the inspector to see a tourist venture. Later Velten, with an acquaintance and a guide, takes the inspector night-hunting with guns and spotlights. The acquaintance has an argument with Velten and leaves. Velten and the guide continue hunting while the inspector sleeps. He is woken by a gunshot; the guide returns without Velten, takes the inspector to the river and leaves. In the morning the guide returns in a dugout canoe to rescue the inspector. A hippopotamus emerges in a mysterious way from the jungle. Earlier in the film someone had emphasized how rare hippos were on that part of the river. Velten (I have to believe in metamorphoses) seems to be dead; however, the truth is left unspoken.

What Are the Themes of Sleeping Sickness?
3 ideas the story keeps returning to, among them Aid & Ethics, Secrets & Morality and Mystery & Metamorphosis.
-
01
Aid & Ethics
The story probes the moral ambiguity of international aid: generous European funds collide with local needs and power dynamics, shaping both medical work and personal choices. It questions who benefits from aid and how oversight can shape care on the ground. The tensions between funding agencies, local communities, and clinic staff drive much of the drama.
-
02
Secrets & Morality
Personal loyalties and professional duties collide when Velten’s affair with a patient yields a child, testing boundaries of doctor-patient trust and the ethics of secrecy. The pregnancy and birth become literal manifestations of the personal costs of work abroad. The inspector's presence further complicates these relationships, exposing secrets that may undermine trust.
-
03
Mystery & Metamorphosis
The film lingers on uncertainty, with Velten’s fate left unresolved as the jungle river and a rare hippo sighting underscore themes of change, transformation, and the unknown. The metamorphosis metaphor hints at shifting borders between professional duty and personal life. The final imagery suggests that some truths may be beyond resolve.
