At an incredibly early age, Marcus and Matthew Owens lost their parents at the hands of vicious mermaids. The brothers grew up with a strong hate for all mermaids and vowed to avenge their parents’ death.
 
After their parents were murdered, Marcus and Matthew were adopted by a wealthy couple who trained them to run a business and hunt fish—particularly mermaids. For many years, they had little to no success in their hunt for revenge.
 
One night, Matthew meets a mysterious young woman at a club in downtown Fort Lauderdale. For him, it was love at first sight.
 
Matthew forgets about all his problems as he and the woman, Gabriella, get to know each other. But Gabriella has a secret. When Matthew finds out, he becomes conflicted, fearful that this secret could damage the relationship between him and his brother.
 
It is said that blood is thicker than water, but will Matthew choose water over blood?
