Hoping to escape the cold in his backyard, Sparky chomps on his magic bone--only to find himself in snowy Zermatt, Switzerland. He befriends Lena, a Saint Bernard rescue dog with a terrible sense of direction. The two, in search of food, quickly get lost. But Lena and Sparky might just be in the right place at the right time for Lena to complete her first ever rescue mission!

Sent to the backyard for breaking a tick-tock-ticking toy, Sparky (an adorable but clumsy sheepdog puppy) immediately begins his favorite activity: diggety-dig-digging. Little does he know, he's about to dig up the most amazing toy ever--a magic bone!

With one bite into that sparkling bone, Sparky is magically transported to London, where he makes new friends, sees the sights, and gets into a bit of trouble. Join Sparky on his adventure to see how he escapes and makes it back home!
