Upon returning from the Second World War, two brothers in arms decide to stop at a brothel to celebrate their homecoming. After years on the frontlines, their sexual appetite is more overwhelming than ever. Tonino, the shyest of the bunch, is hesitant about the excursion while his American friend Pierre can't constrain his enthusiasm. The plot thickens when Tonino discovers that his beautiful fiancé whose picture he has kept through years of battle is the brothel's most prized beauty! This is perhaps Italy's most ambitious adult film ever, shot in 3D, with a cast of Europe's greatest performers. All is fair in love and war, especially at Cathouse '45!
