可爱的训狗师埃里克斯(派屈克·福吉特饰)爱上聪明有才华的女人凯瑟琳(詹妮弗·莫里森饰),两人本到谈婚论嫁的地步,可是他们却开始反思他们的未来。Alex, a lovable, unassuming dog trainer is in love with a great woman - Katherine - smart, talented, from a good family. Katherine adores Alex's quirky sense of humor, honesty and capacity to listen. Having decided to pop the question, Alex is blindsided when Katherine produces a detailed list of well-thought-out "improvements" she feels will tweak Alex on their way to becoming the ideal couple. Alex instinctively rejects the suggestion that he needs to change anything. But with the threat of a new competitor, Alex decides to "do the list." Guided by a coterie of friends that include: Dave, Alex's loyal childhood buddy, best female friend Lily, her husband Michael, and their 8-year-old son, Nicky, Alex's journey has him reconsider and question his beliefs, values and world.
