The beginning pretty much sums up the the movie then it gets into the original part.
Lost and Found
Emmeline and Richard have been stuck in The Blue Lagoon for eight years. They were eight years old when they became stranded on the island with a drunken sailor named Paddy who actually turned out to be a pretty good parent but Paddy died about a year after being on the island. After Paddy died, Emmeline and Richard relocated to another part of the island. They were cousins and all they had was each became teenagers but still just as innocent as they were when they became stranded on the island but with becoming a teenager came puberty and hormones. Their relationship went from being best friends to lovers. They eventually unknowingly conceived a child, a boy who they named Paddy after the last person who took care of them. Nobody ever told them about the birds and the bees so they didn't know that 1+1= always hoped that his father would come for them one day, actually he knew he would but Emmeline had given up and didn't even want to be found. She was so used to their life she didn't see the point in changing it.
In all the years they had been stranded on this island, they had never seen a ship until recently. They didn't even try to be rescued. Emmeline asked Richard to take her to where they had last seen Paddy and he did. Little Paddy was picking berries alone and then he put the berries in the boat without Emmeline noticing. She and Paddy eventually got in the boat and they began to drift in the ocean. Then Paddy through a paddle into the ocean. Emmeline noticed how far they had drifted off so she called for Richard to help. As soon as Richard got to them a shark appeared and Emmeline had to used the other paddle to stop the shark from hurting Richard. Richard got in the boat and they drifted and drifted some more. Then Emmeline noticed Paddy eating red berries, the same red berries she started to eat when they first landed on the island and Old Paddy warned her that she could die if she ate them. It was too late. Paddy had already swallowed some. He started falling asleep and they basically decided that they might as well all die together so Emmeline and Richard ate the berries a ship showed up again and the men on the boat noticed the boat drifting at sea. Four men got into a boat to meet the other. A man got into Emmeline and Richard's boat and an older man with white hair like Einstein asked, "Are they dead?" The man in the boat checked their pulses and replied, "No, just sleeping." The older man then climbed into the boat. He just looked at them and studied their faces. He stroked their hair and wondered, "Could it be them?" Suddenly, Emmeline and Richard woke up, a bit surprised to even be awake and even more surprised to see people standing over them. Richard stared at the older man for a few seconds then a smile came across his face.
"Father?" Richard questioned excitedly.
"Richard?" The old man questioned.
"Father, it is you!" Richard hugged him. "I knew you'd find us!"
"Uncle Arthur?" Emmeline then questioned.
"It's him Em! It's him! I told you he'd come!" Richard exclaimed.
Paddy then woke up from all the excitement.
"Paddy, you're alive!" Emmeline exclaimed. "We're all alive."
"Now, who might this be?" Arthur asked hoping it wasn't what it looked liked.
"He's our son." Emmeline replied.
Arthur looked at the other men. "... Ok. Well, after all these years I think it's about time we get you both home, wouldn't you two agree?"
"We finally get to go home!" Richard exclaimed.
"Yes, yes you do. Oh how I have missed you both so." Arthur said.
"I've missed you every day, father. I never want to go another day without you again." Richard said.
Arthur smiled. "Let's get them to the ship."
"Wait. Can we go back to the island one last time before we go? There are just some things I would like to take with with me." Emmeline asked.
"Sure... I don't see why not." Though, Arthur couldn't understand why she would want to remember this place after being stranded for so long but it was no problem. He was just so happy to have found them.
