War-weary Sergeant Xavier (Marc Zinga) and fresh recruit Private Faustin (Bak) are accidentally separated from their Rwandan battalion inside Congolese territory when it is called out suddenly on nighttime raid. They face a lack of water, food, and threats from malarial fever and jungle wildlife. The two seek to reunite with the battalion by heading westward but must remain wary of interacting with the local population given Congolese antipathy to the Rwandan Army and the presence of irregular rebel factions.
At first the older Xavier is gruff and demanding toward the young private Faustin but a deep bond eventually develops between the two men, especially as Faustin makes critical contributions toward their survival. The film is interspersed with meditations on the horrors that have befallen the region and wider questions of meaning and mercy in times of war. Xavier is particularly haunted by the atrocities he has both witnessed and committed while Faustin is motivated by the murder of his family and a young wife he wishes to see again.
