Lucy Callahan (38) is known as the Sealioness of Aquaria Bay due to her reputation for risk-taking, showmanship and thinking big. She's the founder of Aquaria, the world's most popular public aquarium and marine science precinct. One day, an oil rig ominously parks offshore. Callahan learns that Expedient Energy plans to drill for petroleum in the Aquaria marine park. The threat crystallises when the oil firm take over the Aquaria board, and the extent of their plan becomes known. Callahan dives into battle, prepared to risk everything – even her own safety - to protect her life's work. However, when her partner, Sam, starts running interference, Callahan realises that winning the battle against the oil firm may come at a personal cost, a relationship and possibly a family. How will the Sealioness of Aquaria Bay respond to this dilemma? Will she give in to her Sam's wishes, or fight to the bitter end, even at the risk of her own life.
