We have a brand new exclusive clip from the upcoming DVD set ER: The Complete Thirteenth Season, which will be released in a six-disc DVD set on July 6. Click below to watch this brand new video, which features an intense operating room scene, to go deeper inside this new DVD set.

Shaking things up: Former paramedic, now intern Dr. Tony Gates arrives with a straightforward attitude and a complicated personal life. Except for his devotion to healing, he's Gallant's opposite: brash, cocksure, with a bad-boy past - and maybe he's the right prescription for Neela's broken heart. Really shaking things up: Contentious Weaver leaves County General for a career move you wouldn't expect. And the profound dramas of the outside world continue to make their way to the ER, including a hostile patient whose real condition is a secret even to himself, homeless children who escape to a magic world of their own making, and a Christmas miracle. Then again, miracles happen every day at County General.
