Old Regret follows 11 year old Jed Brown from his troubled life in Swan Hill to a farm in Gippsland where his Uncle trains horses and leads trail rides. Jed learns to ride and helps out on the farm. It's not all fun and games; Jed's main tasks are to pick up manure and clean gear. However, there are wild brumbies in the State Forest adjoining the farm, including a young stallion Jed names 'Regret' after the stallion from the Banjo Patterson poem The man from Snowy River. There are new friends, accidents and incidents, rules broken, and respect gained.
