Trouble at sea

"Go away! We don't want you here," said Carlos.
"Yes, we know," said David. He was very angry with the man.
"We know the plan to buy the old house and build a hotel.
 We heard you. And we saw you put oil in the sea.
We are going to tell the police."

I read Trouble at sea!! 

There are five guys in this story, Faye and her friends.

They are going to swim in the sea. And Faye drive the boat into Jekins Cove.

Then they see a dying bird covered in oil. 

What will happen to them...??
