Charlie is a dispirited bachelor on a losing streak whose only friends are his overbearing Catholic mother, Wendy the webcam girl, and Bill his pet fish. After countless rejections in the dating world, he stumbles upon a website selling companion robots. Intrigued by the idea of finally finding his perfect mate, Charlie designs his companion to meet all his specifications. Initially, the technologically advanced "April" fulfills all of Charlie's desires, but the honeymoon fades quickly when April's artificial intelligence allows her to evolve into a real woman. Feminism is awoken in April as she reads voraciously, makes new friends, and enrolls in a University. Soon April's lust for life begins to surpass Charlie and his lack of ambition. He finds himself lonely again and waiting on dinner with a sink full of dirty dishes. He begins to wonder if "perfectly designed love" is really so perfect.
