Lost in Panic Cruise(2011)

Mystery novelist Liu Feiyun (played by Su Youpeng) is invited to join his friend Dong Lei's (played by Yang Kun) luxury honeymoon cruise. During the day, on the cruise ship, beautiful ladies, wine, blue sea, and white clouds are like a paradise far away from the world; at night, there are masquerade parties, ambiguous flirting and playing, and carnival all night. However, under this glamorous luxury, there is an ulterior dark conspiracy lurking.
