The appeal of this TV movie is in its cheeky attempt to rip off James Cameron's 1997 blockbuster - but on a fraction of the budget. True, the Titanic's sister ship, the Britannic, also sank (in November 1916), but whether the hospital ship was torpedoed because of espionage activities is one of the weaker points of the movie. The special effects aren't bad, but the inevitable romance that pads out the final journey is even more anaemic than the one in Cameron's award-laden epic. Director Brian Trenchard-Smith doesn't bring any depth to the melodrama, but it's still an entertaining voyage.

It was the sister ship of the infamous Titanic... and its final destiny was the same. Experience the true untold story of Britannic, a tumultuous, epic voyage of human passion, courage and betrayal aboard an ill-fated ocean liner bound for a shattering demise. With the world at war, an undercover British agent (Amanda Ryan), embarks the Britannic in search of a German spy believed to be on board to sabotage the ship. Posing as a governess, the undercover agent finds herself falling in love with the ship's chaplain (Edward Atterton). In a stunning discovery, the lovers suddenly find themselves enemies of war. And when a massive explosion deals a deathblow to the ship, their battle becomes one for their own survival. With a dynamic, international cast and a story line that hosts a chilling tale of espionage, politics and romance, Britannic brings one of history's most devastating events to riveting, new life.
