Plot
Cody Griffin is an adopted teenager; his birth mother is a mermaid who left him on the Griffins' boat when he was a baby to avoid being captured. As she left, she was spotted by Mr. Wheatly, a fisherman who became obsessed with finding mermaids. Years later, Cody establishes himself as a quick swimmer on his school's swim team and he has a girlfriend named Samantha. He is under a lot of pressure from a big swim meet coming up and because he is failing biology, he is partnered with Jess Wheatly, the class geek who is a marine biology expert.

After Cody's 13th birthday, he begins to feel strange. As he wakes up in the morning, he turns off his alarm clock and zaps it. Ignoring it, Cody drinks from a milk container, which he notices is stuck to his hand; he later also drinks large amounts of water. He goes to Jess for help, who agrees to figure out what is going on with him as long as Cody teaches him to swim in return. Jess runs various tests, learning Cody can generate electricity, climb walls, talk to fish, swim extremely fast and when sometimes wet, scales appear on his hands and arms. Jess concludes that Cody is turning into a merman.

Despite all the odd things happening to him, as well as the objection of his adoptive parents when they find out, Cody decides to attend the swim meet. He not only wins the meet and beats his teammate Sean, but breaks the state speed record, with his scales appearing. Sean sees the scales and surmises Cody cheated, following him into the locker room. Cody avoids him by sticking to the ceiling, but Sean is determined to find out how Cody cheated. Cody safely makes it out of the school and goes home with his parents after they find out he was not in his room; however, the scales are lasting longer now.

Cody tries calming his parents by claiming nobody saw his scales, but Jess shows up and tells them he saw everything and that people are talking about Cody. Samantha arrives and faints at the sight of Cody's scales. When she awakens, she is freaked out. Cody tells her he is still the same guy and to not be afraid. While sworn to secrecy for Cody's safety, Samantha is disturbed by the discovery and leaves. The next morning Cody takes a swim and meets his mermaid mother; however, Jess's father, who is the obsessed fisherman, spots them and ends the reunion.

Later that day, Cody meets Samantha at the beach. She apologises and they kiss. Cody then walks into the water with her, saying there's something he wants to show her. Cody's mermaid mother appears; however, Cody suddenly gasps in pain and stumbles back to the shore. Writhing on the ground, he tells Samantha to get his parents. After she leaves, Cody's feet turn into flippers. Thinking Samantha came back, Cody is surprised when someone throws a blanket over him.

Jess comes down to where Cody is, but sees he is gone. He then sees his father's boat and panics because his father had seen Cody's fins at the swim meet earlier. Jess's father is planning on using Cody to lure in his mother to prove he is not crazy for believing in mermaids. Jess comes on board the boat and Cody asks him for help. Despite trying to warn the mermaid away, Cody and Jess are unable to stop a fishing net from trapping her. Cody asks Jess to help his mother, so he takes a knife and jumps into the water to cut the net. He frees the mermaid, but his leg gets caught in the net, pulling him under. Jess passes out, but Cody jumps in and brings him to the dock where Jess's father, Cody's parents and Samantha are. Samantha performs CPR, but is unsuccessful. Cody decides to zap Jess's heart, which successfully makes Jess come to.

Cody's mermaid mother shows up again. She discovers her son is still alive and watches him and his family from afar. Cody explains she wants him to go with her because she is the only one who can help him with his changes. Cody's adoptive mother does not want him to leave, but the mermaid telepathically promises to send Cody back before school starts. After goodbyes, Jess asks Cody to tell him and his dad about the aquatic life he sees and Samantha makes Cody promise not to betray her by falling for mergirls. After saying goodbye, Cody and his mother swim off into a life below the surface.
