Custom Post Type Templates from Plugin Folder?

You can use single_template filter hook.

function load_movie_template( $template ) {
    global $post;

    if ( 'movie' === $post->post_type && locate_template( array( 'single-movie.php' ) ) !== $template ) {
        /*
         * This is a 'movie' post
         * AND a 'single movie template' is not found on
         * theme or child theme directories, so load it
         * from our plugin directory.
         */
        return plugin_dir_path( __FILE__ ) . 'single-movie.php';
    }

    return $template;
}

add_filter( 'single_template', 'load_movie_template' );
