Lewis and the girls enter a short film contest held at the JuiceNet cafe, but Lewis, last year's champion, is fresh out of ideas. Rikki and Cleo are roped into doing a film about Emma's mother, but Rikki, thinking that the film is boring, sneaks off to shoot her own film, featuring some impressive underwater footage of sharks. Meanwhile, Zane, ineligible to compete himself, as his father is on the judging panel, recruits Lewis to shoot a film of him windsurfing around Mako Island, recreating (and hopefully beating), his father's windsurfing record of several years before. But things don't go to plan, when Zane falls off his windsurfer, right in the middle of Mako Island's shark breeding ground.
