When Yuma and Kyanna meet in Alice Springs, they realise they could be long lost twins and decide to swap lives, with Kyanna heading to Sydney and Yuma trekking to an outback community to meets her mother for the first time.

Yuma and Kyanna decide to live each other's lives for one week, but realise it's going to be tricky to swap back. Kyanna is faced with an important history test at school and Yuma helps Aaron with a video project about bush tucker.

Yuma and Kyanna are unable to swap places and return home. Yuma finds out she has to try out for the new girls football team. Kyanna becomes closer with Heath, who thinks she has been replaced by an alien.

Kyanna does her best to avoid practicing with Sasha for their dance audition but her odd behaviour draws out her brother and best friend's suspicions. Meanwhile, Yuma learns about bush tucker.

Max helps Ky set up her computer to chat with her sister. Meanwhile, a trip to the water hole with Aaron lands Yuma in hot water.
