Southhampton April 1912. När H.M.S Titanic ska avsegla på sin jungfrufärd mot New York möter White Star Lines ordförande Bruce Ismay skocken av journalister. "Vi har byggt det största, vackraste och mest perfekta fartyget i mänsklighetens historia", säger han. "Här behövs inga livbåtar!". Ombord finner vi en brokig skara människor. Som Molly Brown, en ökänd sångerska som äter män till frukost. Eller Jaime Perse, en desperat ficktjuv som får sitt hjärta stulet av en vacker skandinaviska. Eller Isabelle Paradine, en gift kvinna som ramlar över sin f.d. älskare. Eller Simon Doonan, som planerar att råna alla första klass-passagerare. Eller som Bruce Ismay själv - som får ångra sina ord när Titanic möter den iskalla katastrofen natten den 14:e april. Titanic är mer än bara en katastroffilm. Det är en film fylld av fascinerande levnadsöden och mod som kommer fängsla ditt hjärta.

Queen Mary, Normandie, Mauretania: These great ocean liners of the Atlantic were the largest and most opulent passenger ships ever built. It was as if the finest hotels and most magnificent estates of the Western World had been put to sea. Tour their elite staterooms and swimming pools, and the below-deck immigrant quarters. Hear the real stories of the people who built and boarded them. Visit their renowned ports of call. Follow the great ships as they are drafted into combat, and witness the haunting tragedies that led the Lusitania, Titanic, and Andrea Doria to their doom.

Since their development in the 1850s, ocean liners have been far more than simply passenger ships - they were also the conduit for enormous technological, social and global cultural change. This four-part series is an international story told from a uniquely Australian point of view about the most romantic ships ever built.
