The gap should be between your outside wall and plastic. Outside to in should be wall, gap (1/2" ok) vapor barrier, studs with insulation l, then acoustic barrier for fun, then drywall. If there's nothing between your foundation and insulation then there's nothing to prevent the concrete from soaking up water and insulation following suit.

Also, your bottom plate should be greenboard and I'd put a vapor barrier under it as well.
