The Aurora Borealis is owned by billionaire Anne Lyngstad (Lisa Loven Kongsli), a Norwegian shipping heiress with stage 4 leukemia, and her husband, Richard Bullmer (Guy Pearce), and is en route to Norway for a fundraising gala organized to support the launch of the couple's new cancer research foundation. Lo, along with her photographer ex-boyfriend Ben Morgan (David Ajala), were invited to join the foundation's board members on the cruise in order to publicize the charitable endeavor. But the perpetrator of the crime clearly didn't count on Lo putting her investigative talents to work against them.
