Toby appears to be an ordinary dog living the simple put life, but unbeknownst to his family, he moonlights as secret government operative, Agent Toby Barks.
Unable to support his family in the Australian outback, a man turns to stealing horses in order to make money. He gets more deeply drawn into the outlaw life, and eventually becomes involved in murders. Based on the life of famed 19th-century Australian outlaw Ned Kelly.
