 After a series of ill-fated relationships, Jane (Ashley Judd) has finally met Mr. Right, Ray (Greg Kinnear) - he s emotionally available, and not afraid of commitment. Six weeks into their blissful courtship, he asks her to move in with him, and they start looking at apartments. But little by little Ray starts to pull away, until Jane realizes that once again she s been dumped. Jane s womanizing coworker, Eddie, just happens to be looking for a roommate, and Jane reluctantly moves in. Desperate to understand what happened and get over Ray, Jane comes up with a theory of interpreting male-female relations by observing the behaviors of wild animals. She shares this idea with a friend who works at a men s magazine (Marisa Tomei) and is given an anonymous editorial column devoted solely to her thoughts on the matter. But no one could have predicted the chord she d strike among women with her theory, and the column s wild success makes Jane start to question her conclusions - and opens her eyes to what might be right in front of her.
