For the wedding, they are travelling back to France aboard the RMS Lusitania. Also on board is third class passenger Marinette Cheng, a Chinese artist who falls in love with and meets Adrien, opening his eyes to a world beyond the confines of Adrien's upper class life. But when the Lusitania travels into World War I and is torpedoed by an enemy submarine, their destinies will put them to the test of doing whatever it will take to survive the sinking ship.
