How to set all players to follow a master player

Hopefully some one can share some tips or ideas on how to achieve this. It can be in blue print or c++, really any input is welcome.

I have an architectural multiplayer project and want to have the option let say a key stroke or a button which will make a player the master player and everyone else will be at the same place and see the same view so this master player can talk about the project in a certain area of the project.

Thanks
