Meet the freshman class at Pup Academy, a secret school where pups become dogs. There's goofball golden Corazon, shy sheepdog Whiz, stray boxer Spark and 10-year old Morgan, who is about to discover his secret destiny: his family have been the caretakers of this secret school for generations, and it's time for Morgan to start his new job.

Spark gets into a sticky situation when she makes up an imaginary human best friend to avoid telling her pup friends she's a stray pup, as Morgan endures Charlie's off-the-wall caretaker training.

Morgan struggles to balance his overbooked schedule between work at Pup Academy and his studies at his middle school, much to the frustration of his project partner Izzy, who really wants an A+.
