 Prehistoric cave-stud Ari (Antonio Sabato) wins lovely virgin Listra (Nadia Cassini) in a pig-catching contest, but their attempts at "Ding-Dong" keep getting interrupted by idiot battles between his tribe, The Cave Dwellers, and their neighbors, The Lake Dwellers. Annoyed that hubby would rather make war than Ding-Dong, Listra organizes the women of both tribes to go on strike and "abstain Ding-Dong" until the men stop fighting. It all happens back in the days when men carried clubs and women played ding-dong, an Italian stone-age sex comedy based on the Greek classic "Lysistrata" and filled with shapely cavewomen sporting  70s hairstyles, a gay caveman with the hots for the hero, a title tune that will follow you forever and, of course, plenty of old-fashioned Ding-Dong!
