From underwater cameraman Ken O'Sullivan, Dolphins: Wonders of the Ocean takes viewers on a 20-year journey with dolphins, beginning with an encounter with one lone, lost dolphin in Co. Clare and ultimately to freediving and filming enormous pods off Ireland's coast in the open North Atlantic Ocean. 
 
Cinematic natural history scenes of these charismatic animals hunting in huge pods in the waters around Ireland show insights and behaviours filmed on camera for the first time. 
 
20 years ago, Ken O'Sullivan returned to the West Coast of Ireland to follow his dream of becoming an underwater cameraman. When a solitary bottle-nosed dolphin called Dusty showed up, this beautiful animal became Ken's subject.
