How to make a multiple player animation in roblox studio

OK, so I really want to make a horror game, but when I make a cutscene, I’m confused about how to make a cutscene with the player, for example the Ending cutscene in the game Doors, and the cutscene is like you and your friend “3 friend” inside the car and I’m not too good at coding, so I hope you guys can help me.
