?A group of young people plan their trip on a deserted island. There they get killed one by one.

One movie with that type of plot line is House of the Dead: House of the Dead (2003) - IMDb (http://www.imdb.com/title/tt0317676/)

If you can think of any more details, it might help narrow down which movie you are looking for. Thank you.

Thank you very much for your answer. The movie I'm searching for is really old, from 1980 but I am not sure. I watched it when I was a child with my brother. The story goes like this. From what I recall a group of friends plan to go to a deserted island. Among them there is a pregnant woman. I remember a sequence from the movie where the pregnant woman on a boat stuffs her foot into a bucket where a dead man's head lies. I saw this movie when I was little, I was under 8 so I do not remember much. If you have a clue of what my movie could be, please let me know. I'd like to rewatch it. I have been searching for it for a long time now. I tried movie archives but since I don't remember its title (I assume it's something with "Deserted island..." - only a guess) and being a bit old, I can't seem to find it anywhere. Please help! Thank you in advance!
