"Coup de foudre" seems to happen quite often among some young men and women. This was also very effective for Brooke, an art dealer (Jennifer Aniston), and Gary, who runs a transportation business (Vince Vaughn). After what seemed like a destined love at first sight, the two quickly entered the halls of marriage and promptly took out a joint loan to buy a very grand and spacious house, building their love nest together. But as the saying goes, "It's easy to fall in love, but hard to stay in love!" The romantic and intimate days didn't last long before they gradually began to have many unavoidable conflicts over trivial matters in life. Beautiful and straightforward Brooke finally saw many intolerable bad habits in this man who once gave her so much romance. And Gary, who hoped to find understanding and care in his partner, also began to realize that dealing with women wasn't as simple as he initially imagined.
