Meet Snaggs, the Yorkie mix. After his life on Earth is done, Snaggs crosses the Rainbow Bridge and wakes up in Summerland - the place our beloved pets and other animals go to after they die. Snaggs is determined to find a way back home to his family.

He courageously leaves the safety of the idyllic Garden of Souls and embarks on a fantastical journey in his quest to Spire Mountain where he seeks Shaman the old ram who, according to legend, can help Snaggs rejoin his family back on Earth. Along the way he forges friendships with other animals, such as a ring-tailed lemur, a mountain lion and a giant pterodactyl. Getting back requires a dangerous trek to the kingdom of the dragons, where unbeknownst to Snaggs and his diverse band of allies, there is a revolution brewing and a prophecy that is about to come full circle.
