 It's the "Fremantle" class HMAS "Hammersley"’s final six months before she's decommissioned, and Chief Petty Officer Chris Blake "Swain" is serving aboard her as the coxswain, police officer, chief medic and most experienced helmsman.While he may not get squeamish at such things like blood and gore, the after-effects of such incidents do get to him in his own personal way, especially when a death is involved, and never more so than when the death is that of one of his colleagues.When put in the impossible position of treating two serious ill crew mates who are suffering from a jellyfish sting, "Swain" must decide who is the more serious case and where to centre his attention.
