Grady is a disaster at relationships. Or, well, at starting them. He moves too late or too slow or falls for absolutely the wrong woman. You know, the sort that is committed to someone else, like his brother's fiancée. Claire is done with her veterinary medicine program and is heading on her first dreaded "meet the parents" trip with her boyfriend. Turns out, when you're both working your butts off and never see each other, you may not have noticed that you haven't had a meal together in weeks, forgot the other's birthday, and haven't been intimate in months. Stuck in a pretentious mansion with a snooty future mother-in-law and a man you don't like as well as you thought... and discovering the love of your life isn't the guy you came with, but his brother? Worst and best vacation ever.
