The episode starts with Sirena and Lyla searching for a beautiful shell to use as a gift for the pod while Nixie and Cam race around on their dolphin rides. During their search for the perfect gift, Sirena discovers a secret cave that she has never seen before.

As Sirena is looking around the cave, she notices a shell that is unlike any other shell she has ever seen. She picks up the shell, and as soon as she does, she starts to experience flashbacks from her childhood. Sirena starts to remember pieces of her past that she had completely forgotten about, and she realizes that the shell is the key to unlocking her lost memories.

Sirena decides to keep the shell a secret from the other mermaids and begins to withdraw from the group. Lyla and Nixie start to notice her unusual behavior and become concerned. They try to talk to her, but Sirena is afraid to tell them what she has discovered.

As the episode progresses, Sirena's memories become more vivid, and she starts to understand her true identity. She realizes that she is not just an ordinary mermaid but is, in fact, royalty. Sirena discovers that her father was once the king of the mermaids and that she is the heir to the throne.

With this newfound knowledge, Sirena must decide whether she should reveal her secret to the other mermaids and embrace her royal heritage or keep it to herself and continue living a normal life.

As the episode comes to a close, Sirena decides to reveal her secret to the other mermaids. She explains that the shell unlocked her memories and that she has discovered that she is royalty. The rest of the mermaids are amazed and proud of Sirena for embracing her true identity.

The episode ends with Sirena looking out at the ocean, realizing that her life will never be the same again. She is excited about the possibilities that her future holds and is eager to explore her new life as a mermaid princess.
