Adding a Plugin's Shortcode to Theme's PHP Files

So I found a few threads asking this same question, but none of the answers were helpful to me. I’m having issues with the evolve Bootstrap Slider that I’m not getting help with (like the theme otherwise) so I want to add the Ultimate Responsive Slider to evolve’s header.php file to add the slide to the header of each page as opposed to the body. Assuming it exists, what is the php code for utilizing the shortcode for a plugin. An example of the UR Slider’s shortcode is [URIS id=108]. Thanks for any help.
