Max gets Charlotte, who enjoys love with Ad again, to help him, behind vindictive Emma's back, design a prototype of Juric's Aquajet, just in time as Emma gave both press and client a flippant deadline. Tessa discovers Jacob co-authored the brilliant design. Taunted by the arrogant Wiegersma sisters, Ernst decides to break their sidecar race record. He enlists initially unwilling novice Juup as passenger, but the girls play dirty in the shower and Sjoukje selfishly scolds their risk-taking.
