Jack Linden (Mark Ruffalo) and Hank Evans (Peter Krause) are best friends who both teach at the same university in a small New England town. They both have young children and Jack's wife, Terry (Laura Dern) is close with Hank's wife, Edith (Naomi Watts). But while things appear happy on the surface, there are smouldering pockets of discontent underneath. Financial struggle and domestic boredom has drained the passion from Jack and Terry's marriage, while Hank's numerous infidelities and self-absorption has prompted Edith to find both comfort and sexual fulfilment with Jack. As Jack begins spending more and more time with Edith, it becomes obvious to Terry, whose anger culminates in a sexual encounter with Hank. Now that the deception has come full circle, both couples are left to decide the futures of their shattered unions... 　　译文(2): 杰克 · 林登(马克 · 鲁法洛饰)和汉克 · 埃文斯(彼得 · 克劳斯饰)是最好的朋友，他们都在新英格兰的一个小镇的同一所大学教【资源囤-ZiYuanTun.Com】。他们都有年幼的孩子，杰克的妻子特里(劳拉 · 邓恩饰)与汉克的妻子伊迪丝(娜奥米 · 沃茨饰)关系密切。然而，尽管事情表面上看起来很幸福，但其背后却隐藏着一些不满情绪。经济困难和家庭无聊已经耗尽了杰克和特里婚姻的激情，而汉克无数的不忠和自我专注促使伊迪丝与杰克一起寻找安慰和性满足。随着杰克与伊迪丝相处的时间越来越长，泰瑞也渐渐明白了这一点，他的愤怒在与汉克的性接触中达到了顶峰。现在骗局又回到了原点两对夫妇都要决定他们破碎的婚姻的未来。
