Croc College

Six Australians embark on one of the most thrilling and dangerous training courses Australia has to offer - saltwater crocodile wrangling - and are immediately thrown in at the deep end when an emergency at the farm means they have to help separate two giant males who are up for a blue.

Renee is on the lookout for a missing croc. The men mess up their top-jaw roping practice and they have a runaway croc on their hands. Lyn tells John her tragic secret.

The students learn about life and death on the farm as baby crocodiles hatch in their hands and they have to kill an adult. Repeated fumbling in roping practice leaves John livid with everyone and Lyn's frustration with diminutive Renee reaches boiling point.

Renee catches a croc three times her size but Ryan is struggling. John takes Renee and Ryan on an overnight trip where they must share a motel room with crocodiles and the chance to go to Kakadu is on everyone's mind.

Scientists from the University of Queensland come to the farm to practice artificial insemination techniques. Lyn tells the other students her heart-breaking secret and says she is considering a future in the crocodile industry. John reveals which two students are going to Kakadu.

John takes Lyn and Luke to Kakadu where they raid nests and catch a four and a half metre male croc for research. Lyn returns to the place where her 11-year old granddaughter was taken by a croc and is finally at peace.
