Rogue (2007)

The Austrailian tourist industry has come alive. That is why American travel writer and photographer Pet McKell (Michael Vartan) has journeyed to the Northern Territory. Unknown to him his adventure is about to turn sour. He decides to embark on a picturesque river cruise. While aboard he immediately senses chemistry between the lovely tour guide Kate Ryan (Radha Mitchell). She has lived in this area all of her life and is quite versed in the local lore and sites. Other tourists pack the boat. This group is thrown for a loop when an unexpected bump on the bottom of the boat causes it to capsize. Luckily for them, there is a small island easily reached. However, as night begins to fall, the groups suddenly realizes that it was not a submerged rock that caused their plight, it was a gigantic alligator.
