Xtremely Wild heads back to the site of the Exxon Valdez oil spill. Otters seem to be thriving years after one of the worlds worst environmental disasters. But a closer look reveals the oil is still here and the otters generations later are still carrying the scars of that day. Join the team as we race to out-smart the otters in an effort to catch them with underwater nets sometimes it works, most times it doesn't. And later we head to Seattle where Nina the gorilla fights to stay alive after a serious kidney infection. Some tough decisions to make in the operating room as Xtremely Wild helps as a gorilla goes down.
