OH MY GOD HELP!!

Saw this film last night...hope this helps:-

On Richards return, Lilli decided she really liked Richard and they both decided they want to be man and wife (they held a self styled wedding) on the island and exchanged hand-made rings.
They also gave into their feelings and discovered how to 'mate' with each other (that's what they called it).
After some more time on the island, a ship arrived with a Captain, the Captains daughter and some crew (these arrived for a few days only to obtain some fresh water supplies from the island). Both Lilli and Richard asked if they could go with them to return to civilization.
The daughter fancied Richard and he was keen on her as he'd never seen another young lady before, wearing make-up and pretty clothes. However, during the daughters attempt to seduce him, he realized he only wanted to be with Lilli and didn't 'mate' with her.
Towards the end of the film Richard tells Lilli the crew will be leaving the following day, but Lilli says she won't be leaving with them and she wants Richard to teach her the lullaby that Mother would sing to them, as she would need it in the future. When Richard asks why, she tells him she is going to have a baby and won't be leaving the island, as she wants the baby brought up in surroundings where there is peace, no guns and fighting. Richard agrees and stays with her.
The ships sails away... We then see Lilli, Richard and baby swimming and playing on the island...THE END !
