For three young soldiers, Aleš, Ota, and František, this means surviving ten days in the forest, avoiding capture or being lured into a trap, and reporting daily on the observed object, all with only two days' worth of food rations. Only a well-coordinated team can accomplish such a task. However, all is not well between Ota and František—their problem is named Marie.
