Above the crystal-blue waters of North Queensland, Captain Morgan Pentland patrols the vast Australian coastline. When Customs Agent Rafe Daniels joins her crew, she is immediately suspicious. Why is he boarding her plane when she isn't there? And why is he asking so many questions? What Morgan doesn't know is that Rafe has her under surveillance. Critical information about their Border Watch operations is being leaked and she is the main suspect, but when Morgan and Rafe are shot down in a tragic midair attack, they realise they have to start working together - and quickly. One of Australian's most loved icons is the next target and they have only nine days to stop it. Will they uncover details of the plot in time, or will the tension that is growing between them jeopardise everything?
