Forty-year-old Kent is an unmarried children’s show writer living alone with his cat in Los Angeles. He spends his days sketching gag cartoons and bouncing ideas off his hyperactive friend, Kev, and his nights staving off loneliness in Internet chat rooms. When one of Kent's online acquaintances, environmental journalist Kate, crashes at his house for the weekend, he finds himself attracted to her coquettish manner and frank emotional openness but sexually frustrated by her fidelity to a distant boyfriend.
