Though very exhausted from their long journey to and through the land of Mordor, Marshall helps Chase the rest of the way up the slopes of Mount Doom to destroy the One Ring. And the only way to do that is for Marshall to carry Chase on his back.

During an invasion of the city of Foggy Bottom, Marshall stops Chase from succumbing to the power of the One Ring. When all hope feels lost, our favorite clumsy yet lovable Dalmatian reminds our tough and brave German Shepherd of why they are going through their journey and that there's always hope.

As Chase the German Shepherd pup comes to terms about his destiny, his best friend Marshall the Dalmatian chases after him. And after saving his friend from drowning, Chase sees just how much of a good friend Marshall is to him and takes him with him to destroy the One Ring for good.
