Accused of fraud, Ivan Lausman aims to end it all by driving his car into a river. When he's washed up 10km downstream, alive and well, the Aquarians know he's a land-lubber with a residual Aqua gene.

Lausman is enjoying nix life and Jara, who is trying to track him down, is humiliated when a picture of her quarry, taken by a tourist, appears in the paper. Trpelka nearly drowns during a stake-out.

Jara breaks into a boat belonging to Lausman's protectors Eduard and Johana, steals some strange food items and sends them off to the lab. Dr Jech is confused by the results of his tests on Lausman.

Eduard is determined to get to the truth about the magic water of Vysehrad and starts a petition to propose the 'coming out' of the nixes. Lausman plans a new venture in the bottled water industry.

Magda instructs that Lausman should be 'dried out', but when his test results confirm his exceptional genetic status, she tries to rescind the order. Eduard's closing in on the entrance to the waters.

Magda tells Lausman she knows where the rest of the ancient scrolls are, but when he takes the bait and volunteers to retrieve them, peril awaits. Jara's hot on his heels, but will she arrive in time?
