Heres the plot according to wiki...
The plot chronicles the romantic misadventures of several individuals in their twenties and thirties. The common thread is that one person in each relationship is more "into" the other person than vice versa. At the core of these multiple stories is Gigi (Ginnifer Goodwin), a young woman who repeatedly misinterprets the signs that men give her about their level of interest in her. The more experienced and romantically successful Alex (Justin Long), the manager of a bar, advises her on how to understand men.
Other plotlines include married couple Janine (Jennifer Connelly) and Ben (Bradley Cooper), who are going through a rough patch—leading him to flirt with Anna (Scarlett Johansson), an aspiring singer. Anna, in turn, is dating Connor (Kevin Connolly), but is clearly less into him than he is into her. The final major plot arc is Neil (Ben Affleck) and Beth's (Jennifer Aniston) story. They have cohabited for several years, but break up when Beth desires to get married and Neil refuses.
Drew Barrymore, one of the film's producers, is also featured as a newspaper editor who helps Connor promote his real-estate business. She herself has trouble comprehending the semiotics of dating.
