圣人文森特

玛姬（梅丽莎·麦卡西 Melissa McCarthy 饰）和儿子奥利弗（杰顿·李博赫 Jaeden Lieberher 饰）两人过着相依为命的生活，在巨大的生活压力之下，玛姬不得不在医院里加班加点的工作赚钱，自然也就无力照看年幼的奥利弗。 　　于是，玛姬将奥利弗托付给了邻居文森特（比尔·默瑞 Bill Murray 饰）——一位看上去风度翩翩的优雅老人。然而，真实的文森特脾气暴躁，酗酒如命，沉迷赌博，甚至和脱衣舞女达卡（娜奥米·沃茨 Naomi Watts 饰）一起带着奥利弗去夜总会鬼混。奥利弗目睹了文森特的种种“恶行”，却用一种孩童式的善意目光进行着解读，随着时间的推移，文森特和这个小男孩之间建立起了坚实的友谊。Vincent is an old Vietnam vet whose stubbornly hedonistic ways have left him without money or a future. Things change when his new next-door neighbor's son, Oliver, needs a babysitter and Vince is willing enough for a fee. From that self-serving act, an unexpected friendship forms as Vincent and Oliver find so much of each other's needs through each other. As Vincent mentors Oliver in street survival and other worldly ways, Oliver begins to see more in the old man than just his foibles. When life takes a turn for the worse for Vincent, both them find the best in each other than no one around them suspects.
