Sweetie Drops (we know her as Bon Bon today) is an agent for Tartarus, a secret monster prison created by order of Princess Celestia.

Together with a ragtag group, consisting of a narcissistic Pegasus, a greedy griffon outcast, a mystical Unicorn; and eventually a scatterbrained inventor, a raggedy drunk, and a peculiar Diamond Dog, Sweetie must take down the biggest threats to Equestria and keep them under watchful eye at the most secure location in all of Equestria.

Unless, of course, the biggest threat is the Agents of Tartarus themselves.
