Tam and Steve decide their only option is to sell "Henderson's Point" as they know how much trouble the town is in, but then Mrs Phelps arrives from the museum and tells them the markings are authentic and over 2000 years old.
Mrs Phelps suggests selling to the government, as they would preserve the land and not destroy it.
Tam and Steve discuss selling to the government with Wal who agrees to look into it for them.
Wheeler arrives to finalise the details, Tam tells him that they won't sell to him, he goes mad and Mike throws him out.
Mike and George are called away to a car smash on the other side of town.
Char and Cowboy have a heart to heart and agree to just remain friends.
While Mike is away at the car smash and Wal in the city sorting out the government offer, Wheeler comes back and threatens to blow up the cave unless Tam and Steve sign "Henderson's Point" over to him by ten o clock, when Tam tries to contact Mike, Wheeler tells her not to bother as he has been called away.
Andy sees Wheeler and Rutt at the "Point" getting ready to blow up the cave, he tries to stop them and Wheeler takes him hostage.
Tam and Steve gather the local kids to help out as Brains leads a parade of five.
Wheeler is about to have the cave blown up when Tam and Steve arrive, they are shocked that he has kidnapped Andy and demand his release before they sign, Wheeler just agrees to untie him, and realising Steve is stalling, tells Cooper to blow the cave.
The parade kids arrive there is a lot more now, including Char and Regina and they stand in front of the cave, Cooper refuses to blow it up with them standing there, so Wheeler gets Rutt to threaten them with his gun.
Mike and George realise they have been sent on a wild goose chase and head back.
Cowboy gets bored studying and goes to join the parade, Barry tells him they are all up the "Point" saying Mr Wheeler is going to blow it up, Cowboy heads straight to the "Point".
The parade kids move out of the way of the cave scared of Rutt and his gun and Wheeler gives the order to blow up the cave.
Cowboy rides up on his horse and grabs the plunger throwing it over the cliff, the rest of the kids battle with Cooper and the others and Wheeler and Rutt make a run for it.
Cowboy catches Rutt and Mike and Steve finally get Wheeler who offers to do a deal with them.
Tam and Steve decide to leave with Wal for a new life in Melbourne.
Mike and Steve pledge to be friends forever.
Hendersons Point is finally sold to the government, to be preserved and Haven bay will be a tourist town.
Cowboy gives Tam his hat and her first proper kiss.
Char gets a new job in a store, and Brains gets a new gang and the new name of "Bronco". The Henderson Kids say a tearful goodbye to Haven Bay, Uncle Mike and all their friends.moreless
