Straight-laced, type-A personality Joy Miles has to take an unscheduled road trip to drive her forgetful, yet opinionated, mother-in-law, Loraine, from Louisville, Kentucky to Savannah, Georgia. Although initially impatient and frustrated, Joy begins to realize her true affection for Loraine as she takes a front-seat-view of how this strong-willed yet free-spirited woman manages the emotional transition of learning to live life after losing her spouse. Despite their many differences, and with light-hearted adventures at every turn, they discover how much they respect and even need each other.“这块无事牌是墨玉加上血玉共同融合而成，会随着人体的温度显现其中的内容，并且这是一件千年前的宝贝，没有人知道是如何做到的，但根据史书记载这东西一直都在一个神秘组织手里，最后组织散尽家财，这东西也就流落了出来。”经理解释着。
