Programming A Reset Scene

I am working on a project that moves the camera through a series of checkpoints. Each checkpoint has a series of instructional animations and I am trying to make it so that as soon as you move forward or backwards from a checkpoint, the scenes all reset themselves to Animation Frame 1. Does anyone have any suggestions? Here's my code -- I know animation.Rewind can reset scenes but not sure how to point Unity to set every object in the game with animation to its starting frame.

 private var sceneMoverScript;
 private var wayPointScript;
 
 function Awake()
 {
     wayPointScript = GameObject.Find("Main Camera").GetComponent("waypointMover");
     
 }
     
 function Update () 
 {
     if(Input.GetMouseButtonDown(0))
     {
         var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
         var hit : RaycastHit;
         if (Physics.Raycast (ray, hit, 100))
         {
                 if(hit.collider.gameObject == gameObject)
              {
                                  wayPointScript.moveToPreviousWayPoint();
                                     animation.Rewind;
             }
         }
     }
 }
