A uniquely funny and moving story about Greg, a high school senior who avoids deep human relationships as a way to safely navigate the social mine field that is teenage life. In fact, he describes his best friend Earl, with whom he makes short-film parodies of classic movies, as being 'more like a co-worker'. But when Greg's mom insists he spends time with Rachel, a girl in his class who has just been diagnosed with cancer, Greg discovers just how powerful and important true friendship can be.
