Holiday trip

You are playing as Joanne (the woman in the photo). You have taken a holiday to a beautiful island. When you are walking along the beach on the second day of your trip you meet a local man who offers to take you out on his boat. You pay him a few pounds and happily climb aboard his boat. Joanne finds herself a quiet spot on the deck and lays down on her beach towel to do some sunbathing. Once he has taken you out to sea, away from any help the local man anchors the boat and several of his friends who have been hiding below deck come up on deck. What do they want with you?
