Alan Corcoran

Mary is trapped in a toxic friendship. Miriam, with her chain-smoking and vicious tongue, is that toxic friend. Morning tea and vitriol. There is no smoke without fire.

Alan Corcoran's 500-km length of Ireland sea swim has all the hallmarks of a fascinating documentary. Unsinkable explores a person's journey through grief, channelling negative emotions into a meaningful, hopeful, inspiring adventure.
