Autumn 1944, the Slovak National Uprising is suppressed and the fighters must withdraw to the mountains. Commander Repta’s unit takes along the thirteen-year old Zuzka, who lost her home and all her relatives in the rebellion. But the enemy brutally pursues them and Repta therefore must divide his unit. The withdrawal is covered by the group commanded by Peter, whose members almost all die in an exchange of fire with the German soldiers. The only one to survive is the severely wounded Peter. Zuzka, of whom everybody forgot in the zeal of the fight, hides him from the Germans. As soon as Peter is able to walk, he and Zuzka set off to meet their co-fighters.

如果我有一支枪，中文剧情：这是关于一个男孩在战争时期梦想当英雄的悲喜剧故事，他们每天都面临着战争和乡村生活的严峻事件。 此片于布拉格之春后4年上映，或多或少折射出捷克人和斯洛伐克人一种无奈的民族情绪——斯洛伐克人的小提琴，德国人来了，演奏莉莉马莲，俄国人来了，演奏喀秋莎。
