在这部大意过头犯罪/惊悚/剧情片中,《大意过头》讲述的是关于骗子们的故事。在这里，唯一的事实就是一切都有可能是骗局。自成人之后，埃尔内斯特一生当中只做过一件事：欺骗。他了解一个名叫独臂人的老骗子的骗局内情。他们所有的作案对象都属于社会中下阶层，而且他们的作案规模很小。不久之后，独臂人将埃尔内斯特介绍给一个叫做费德里格的骗子，他是独臂人所见过最“出色”的骗子，而且此人外表高雅，却极其狡猾。如果不是 费德里格的旧情人皮拉尔的出现，他们的生活将一帆风顺。皮拉尔给费德里格提供了一个在骗子们看来是非同一般的情况，这无疑给他们的收手带来沉重的一击。
In a flashback, Ernesto, a young con man, tells us how he got to the edge of a big score: childhood in an orphanage, youthful smash-and-grab burglaries until his partner is caught, then tutelage from Lefty, an aging swindler. After some years of success, they're joined by Federico, the best, a true artist. Things go well until Pilar, a woman from Federico's past, re-enters his life with a proposal to con a golden goose - a swindle that will put them all on easy street. A double-cross may be in the cards. The flashback over, can Ernesto hold his own in the present?
不看到最后都猜不出结局。
