Multiple modals overlay

I need that the overlay shows above the first modal, not in the back.

$('#openBtn').click(function(){
        $('#myModal').modal({show:true})
});

<a data-toggle="modal" href="#myModal" class="btn btn-primary">Launch modal</a>

<div class="modal" id="myModal">
        <div class="modal-dialog">
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
          <h4 class="modal-title">Modal title</h4>
        </div><div class="container"></div>
        <div class="modal-body">
          Content for the dialog / modal goes here.
          <br>
          <br>
          <br>
          <br>
          <br>
          <a data-toggle="modal" href="#myModal2" class="btn btn-primary">Launch modal</a>
        </div>
        <div class="modal-footer">
          <a href="#" data-dismiss="modal" class="btn">Close</a>
          <a href="#" class="btn btn-primary">Save changes</a>
        </div>
      </div>
    </div>
</div>
<div class="modal" id="myModal2" data-backdrop="static">
        <div class="modal-dialog">
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
          <h4 class="modal-title">Second Modal title</h4>
        </div><div class="container"></div>
        <div class="modal-body">
          Content for the dialog / modal goes here.
        </div>
        <div class="modal-footer">
          <a href="#" data-dismiss="modal" class="btn">Close</a>
          <a href="#" class="btn btn-primary">Save changes</a>
        </div>
      </div>
    </div>
</div>

I tried to change the z-index of .modal-backdrop, but it becomes a mess.

In some cases I have more than two modals on the same page.
