When an apocalyptic catastrophe decimates the land, a lucky few escape on a souped-up cruise ship called the Catalina. After 16 years, the strain begins to show in a floating world of distrust and shifting allegiances.
A young mechanic named Esther wants to prove herself, but she tends to bash things up in the name of progress. When disaster strikes the Catalina on Esther's watch, she must risk everything to fix her mistake. She sails in search of help and encounters a mysterious metropolis called the Galaxy Flotilla. The inhabitants are keen to parade their lives of luxury, but they'll want something in return for their warm welcome.
A new storm is brewing on the post-apocalyptic ocean. Can Esther save her friends aboard the Catalina before it's too late?
