Poppy is a crazy cream golden retriever who is loveable yet greedy and spoilt. When her family head to a Safari Park for a fun-filled day out, her day does not go as expected. Instead of meeting new animals, she is left behind at a dog kennel.
Fearing she is being punished for being naughty earlier, Poppy panics. She is also told about a mysterious animal called Cain, the King of the Safari Park, but something has happened to him and nobody at the kennels knows what this is or what he has done.
Poppy is desperate to rejoin her family. She persuades the other dogs to help her escape by promising to find out what has happened to Cain. She meets a puppy called Harley who is also a cream retriever. Harley has lost his family too. Now Poppy not only needs to find her family, but help Harley find his loved ones and also get to the bottom of the mystery surrounding Cain. How is she going to manage this when dogs are not even allowed inside the Safari Park?!
