Dino Cassio

Engineer Quiller has become rich by selling his completely indestructible shop-window glass to jeweleries around the world. But this got him lots of enemies too: the insurance agencies, who've lost hundreds of customers, and the burglarers. When he temporarily looses his memory and voice in an accident, of all people, a family of thieves finds and cares for him - believing he's a pocket-picker. Things get complicated when he falls in love with his host Tilli.

Cristina is a rich, spoiled princess visiting Rome with her royal parents. The mission of their visit is to marry her off to a super-wealthy corporate type and thereby start to turn around the losses their small kingdom is experiencing in its casino business. These less-than-noble intentions get derailed when Barnaba, a zany bus driver enters their lives and falls madly in love with the gorgeous Cristina. He is nuts enough to succeed in this romantic chase after royalty, as love seems to fuel his determination to rid Cristina of her elitism and to make her see his own irrepressible attractions.
