Screenwriting : Pitching the drama by Bill Albert

I've been working at a written pitch for my first drama. There have been no requests yet, but the feedback has been very positive and encouraging. The two producers both commented that they felt they would like more details on the "action" of the story and how it all comes together. I had originally included the character arcs and how they all pay off and am trying to come up with a better way to explain it. In the most recent version I tried dividing them up and describe the character arcs in one point and how it all comes together in another, but it just keeps feeling repetitive.

The advantages the producers like is it's a relatively small cast of characters, all university students, happens in a single day, and during the final performance of a play so there's plenty of drama happening on and off stage,

Anyone have any experience at pitching the drama and the best way to describe it?
