You might want to check the Animation controls if you have animated humanoid model running down the cave.
Also, when you position your object, position the camera behind it.
`Using the example RPGamer posted.
Position Object 1,plx#,ply#,plz#
Position Camera plx#,ply#+50,plz#-200
Point Camera plx#,ply#,plz#
that should make the camera stay behind and a bit higher than the object. Point camera logically points the camera to the object's position. Oh, I just made up the +50 and -200, you might want to tweak those... cos I have no idea how big the cave is.
