Sean Walker (Jason Ritter) is the typical boy next-door as well as a somewhat geeky Computer Science graduate of MIT. A reformed hacker, he now freelances as a video game programmer. Sean grew up in a poorer suburb of Chicago. With a realized gift for computer programming, he spent his time in the school’s computer lab because his family couldn’t afford a computer of their own. He only got through college because of three jobs and financial aid. He’s now in a relationship with Lelia Buchanan and is confident she’s the woman for him. He was ready to propose when she disappeared.
