1750, Republic of Venice. The young Giacomo Casanova is hired to keep an eye on the family that owns the infamous Ca'Dario, considered by most to be cursed or perhaps a place where some ignoble act against the Serenissima is about to be orchestrated.
To his support, a strange group arrives, almost providentially, and annihilates the threat with incredible efficiency. Giacomo is particularly fascinated by the handsome Nicolò Di Genova, with whom he would not disdain the company in his rooms. However, all his attempts at seduction are useless, as the handsome Nicolò only has eyes for his Yusuf Al-Kaysani.
2025, Venice. Nicky and Joe return to Venice on the trail of human traffickers who use Ca' Dario as a base, using its reputation as a cursed house as a cover. For the two, it is certainly no surprise that history tends to repeat itself. They did not expect to meet Giacomo, a young architect interested in studying a historic building like Ca' Dario. Giacomo resembles in every way the Giacomo Casanova met in the 18th century, but he is completely unaware of this aspect and above all unaware of the danger he could run into by sticking his nose into Ca' Dario. He is in fact saved by the two immortals from a terrible end and the traffickers are discovered and arrested thanks to the teamwork. This Giacomo too remains fascinated by the handsome Nicky, discovering once again that the immortal's love for Joe is so strong that he does not notice Giacomo's obvious flirting.
