Trading the desert for the steamy tropics of Far North Queensland, Lucky and Meg hit the road – and the river – on a mission to find Meg's mum. Trouble is, Meg's mum has disappeared into the rainforest, Meg might be pregnant, Lucky is hiding something about his own sordid Queensland past, and Toby and Suzie are threatening to withdraw his right to contact Billie.

Beginning their search in Queensland for Meg's mum, Lucky struggles to manage his relationship back home; Meg is startled by someone who followed her from Karingunna.

Meg continues the search for her mom in Cairns; Lucky tries to lay low to avoid his dubious past.

Lucky and Meg head out of Cairns; Lucky's best forgotten past catches up with him.

Wounded in the rainforest, Lucky is desperate to return to civilization; Meg wants to push on as they get close to finding her mother.

Meg and Lucky finally make it to the Wellfulness Commune, but don't get the reception they were expecting.

Trapped at the Wellfulness Commune, Lucky starts to unravel its secrets as Meg finally gets the chance to speak to her mother.

After escaping the commune, Lucky and Meg race back to Sydney hoping to make it in time to meet Billie at the airport.
