When the police receive an emergency call placed from Wonderland Avenue Los Angeles, they were ill prepared for the carnage that awaited them, a brutal blood bath that had left four dead and no reliable witnesses. Wonderland is based on a true story that took place in July 1981, and provided as its chief suspect one of the most famous male stars in the porn business, John Holmes. Wonderland is a slick, brutal, dramatic thriller, acted with seedy perfection by Val Kilmer at its nihilistic heart.
