Three travelling showmen hailing from the mysterious land of Réndøosîa (a fictional Eastern European country that experiences an unusually high rate of natural disasters to the point that its flag is always depicted with a hole in it, as well as being at war with the neighboring nation of Grimzimistan), the three Adrenalini brothers (Xan, Enk and Adi), tour around the world staging ridiculously hazardous stunts, usually succeeding (but more out of luck than skill). In their travels, the Adrenalinis have visited many real countries and places in the world, and even many periods in history (and, in some cases, fiction).
