A group consisting of stand-ins for the lead actors, and usually the 2nd or 2nd 2nd AD.

After the actors and director have blocked the scene, the 1st AD sends them off to make-up while the crew lights the scene. In order to see how the light interacts with the characters, stand-ins will, you guessed it, stand in for the cast.

The opposite of First Team, which is the on-screen actors and other key personnel.
