Adult siblings Sammy Prescott and Terry Prescott have had a special bond with each other since they were kids when their parents were tragically killed in a car accident. That bond is why single mom Sammy, who still lives in the family home in Scottsville, upstate New York with her eight year old son Rudy, is excited to hear that Terry, who she has not seen or heard from in a while, is coming home for a visit. That excitement is dampened slightly upon Terry's arrival, when she learns that he, broke, is only there to borrow money. As adults, Sammy, who works as a lending officer in the local bank, is seen as the responsible sibling, while unfocused Terry is seen as the irresponsible drifter. Regardless, Sammy welcomes what ends up being Terry's longer than planned visit if only so that he can help take care of Rudy, who has no adult male figure in his life. Rudy has never known his deadbeat biological father, with whom Sammy wants nothing to do. As Terry - acting as the supposed adult male role model figure - gets to know Rudy, and as Sammy deals with the issues in her life which includes figuring out what her relationship to longtime friend/lover Bob Steegerson means, and how to deal with her straight-laced micro-managing new boss Brian Everett, the maturity level between Sammy and Terry is not as far apart as it appears on the surface. 请再靠紧我——意外的惊喜！。我办事你放心。他不是我父亲！。还好有你。些许感叹。quite a late dinner, huh?。《你可以信赖我（You Can Count on Me）》：不靠谱兄妹【第16届圣丹尼斯电影节最佳编剧奖】。我找你好多年---《你可以信赖我》。 萨米（劳拉·琳妮 Laura Linney 饰）和特里（马克·鲁弗洛 Mark Ruffalo 饰）都是无依无靠的孤儿，这一共同点让他们彼此之间产生了坚固的友谊。无奈岁月无情，将两人分隔两地，多年后，萨米成为了一个勤恳又贤惠的单身母亲，带着8岁的儿子鲁迪（罗瑞·卡尔金 Rory Culkin 饰）享受着安稳又平静的生活，而特里却四处流浪，在肆意放纵的同时麻烦缠身。 一次机缘巧合之下，这两个童年相依为命的孤儿重逢了。在萨米的家庭里，特里找到了久违的温暖和安宁。面对邻居们的质疑，萨米毫不犹豫的站在了特里的这一边，为了成为一个“配得上”这个家庭的男人，特里也在不断的做着改变。可现实并不如想象中的美好，即便萨米和特里两人相互信任和依靠，可问题和麻烦还是接踵而至。
