50s or 60s movie

I just got done watching this movie on TV but the guide was wrong and I can’t seem to find the real title anywhere. 🙁 Basically, these kids’ parents die so they start holding adults captive to be their “parents”. Every time one tries to run away, the kids stop them and if all the kids vote that they don’t want one of the adults there, Peter(the eldest) kills the adult but the kids think that Peter just lets them be free. They’ve also had a woman named Caroline captive for 5 years. I liked this movie but I didn’t understand the ending. If you know this movie, please tell me the title. Thank you!
