In the West African nation of Benin, Finnish immunologist Anu Kantele is developing a cure for diarrhea, a disease which kills thousands of children in the region every year. With Beninese adults immune to the cause of the disease, Kantele has devised a program that invites Finns to travel to Benin for a combined vacation and vaccine trial. People We Come Across follows one such test group, and is an entertaining and thought-provoking exploration of research ethics, tourism and the relationship between Europe and Africa.
