Wis. Stat. § 805.10: Examination of witnesses; arguments.

Unless the judge otherwise orders, not more than one attorney for each side shall examine or cross-examine a witness and not more than 2 attorneys on each side shall sum up to the jury. The plaintiff shall be entitled to the opening and final rebuttal arguments. Plaintiff’s rebuttal shall be limited to matters raised by any adverse party in argument. Waiver of argument by either party shall not preclude the adverse party from making any argument which the adverse party would otherwise have been entitled to make. Before the argument is begun, the court may limit the time for argument.
