在摩洛哥、墨西哥和日本发生的三个故事。 理查德（布拉德·皮特 饰）和妻子苏珊（凯特·布兰切特 饰）因为婚姻危机，去摩洛哥旅行，苏珊在旅行车里遭遇枪击，为了医治苏珊，一车美国游客不得不在摩洛哥的小村滞留，而警方也将此次事件上升为恐怖袭击，展开了调查，其实真相却惊人的简单。 理查德夫妇滞留在摩洛哥，影响到了家里的孩子们，墨西哥保姆为了参加儿子的婚礼，只能让她的侄子（盖尔·加西亚·贝纳尔 饰）开车带着她和孩子们一起去，但是，从墨西哥过境回来的时候，他们遇到了麻烦，警方怀疑她绑架美国小孩，事情开始不受控制。 日本，聋哑少女千惠子孤寂地生活在无声的世界中，母亲的自杀使她和父亲的沟通越发困难，由于自己的残疾，她也得不到异性的关注，性格越发叛逆。于是，她用自己的方式，和世界沟通交流。4 interlocking stories all connected by a single gun all converge at the end and reveal a complex and tragic story of the lives of humanity around the world and how we truly aren't all that different. In Morocco, a troubled married couple are on vacation trying to work out their differences. Meanwhile, a Moroccan herder buys a rifle for his sons so they can keep the jackals away from his herd. A girl in Japan dealing with rejection, the death of her mother, the emotional distance of her father, her own self-consciousness, and a disability among many other issues, deals with modern life in the enormous metropolis of Tokyo, Japan. Then, on the opposite side of the world the married couple's Mexican nanny takes the couple's 2 children with her to her son's wedding in Mexico, only to come into trouble on the return trip. Combined, it provides a powerful story and an equally powerful looking glass into the lives of seemingly random people around the world and it shows just how connected we really are.
