Comment redirect

Hello guys!

I have a post and after one comment i would like to redirect the site to other page. Only one post in my site and i have around 10 pages. Maybe I found the .php file (comment-template.php) where should I change the things but I’m not php coder I dont know what and how?

EDIT: I forget to say I use twentytwelve template.

Best regards,
