Siren is an American fantasy drama television series that follows Ryn Fisher (played by Eline Powell), a young siren who comes to a small coastal town looking for her abducted older sister. The series premiered on Freeform on March 29, 2018. The first season included 10 episodes. In May 2019, the series was renewed for a third season which premiered on April 2, 2020. The series was canceled in August 2020.
Premise The coastal town of Bristol Cove, Washington, known for its legends of once being home to mermaids and mermen for centuries, is turned upside down when a mysterious young woman named Ryn Fisher (Eline Powell) appears and begins wreaking havoc upon the small fishing town to look for her captured older sister Donna (Sibongile Mlambo) who was abducted at the hands of the local military. Marine biologists Ben Pownall (Alex Roe) and Maddie Bishop (Fola Evans-Akingbola) work together to find out who and what drove this primal hunter of the deep sea to land.
By Season Two, more merpeople started appearing in Bristol Cove due to the pollution in the nearby waters and the sonic waves from the oil rig. Meanwhile, Pownall's paralysis is gradually being counteracted by Ryn's mermaid stem cells.
In Season Three, Ben, Maddie, and Ryn contend with the mermaid Tia (Tiffany Lonsdale) who plans to coerce all merpeople tribes/colonies to join her in her fight to overthrow humanity. And Ryn's daughter, who has been carried by a surrogate, must be protected at all costs. To further escalate matters, Ted Pownall has finally acknowledged the existence of merpeople and seems to be on a dangerous path, just as his paternal great-great-great-great-grandfather Charles had.
Cast and characters Main Eline Powell as Ryn Fisher, a strange young adult mermaid with a dark secret. She comes ashore in search of her elder sister, who has been accidentally captured by fishermen of the North Star fishing vessel. She eventually comes to realize that not all humans are murderous, and becomes Ben and Maddie's lover. To help Ben's mother Elaine, she willingly donates her aquatic stem cells to help counteract the paralysis in Elaine's legs. Upon mating with a bearded merman of another colony when she couldn't find Levi, she has a daughter named Hope. Alex Roe as Ben Pownall, a marine biologist who helps Ryn when she first comes to shore. He is entranced by her melodious, irresistibly hypnotic siren song, which she deploys on him as a defense mechanism without knowing the full extent of its effects on humans. Ben later becomes Ryn's lover, and his struggle to untangle his affection for her from the obsessive thoughts that result from hearing her siren song becomes a significant part of his character arc. To help Ryn and her kind, he resorts to injecting himself with the stem cells of a partially transformed mermaid corpse and subsequently develops abilities found in merpeople – heightened hearing and reflexes, accelerated healing, and the ability to hold his breath for extended periods of time. At the end of season 3, following the fight against Tia, Ben goes missing in the ocean. Fola Evans-Akingbola as Maddie Bishop, a marine biologist and Ben's girlfriend in season one and two. She works at Bristol Cove Marine Research Center with Ben. Her father is the sheriff of Bristol Cove. Her estranged mother is Susan, who returns after nine months in Season 2. Like Ben, Maddie is entranced by Ryn's melodious, irresistibly hypnotic siren song but doesn't seem to develop the same feelings of possessiveness as a result. She later becomes Ryn's lover. Ian Verdun as Xander McClure, a deep-sea fisherman who seeks to discover the truth about the existence of mermaids and mermen. He eventually joins the Bristol Cove Sheriff Department in an attempt to save those he cares about more against the enemy merpeople. In season 3, following the death of Dale, Xander is sworn in as the new Sheriff of Bristol Cove. Sibongile Mlambo as Donna (season 1; special guest star season 3), a mystical and deceptively powerful mermaid who is Ryn's older sister. She was unintentionally caught in a fishing net and taken by the military. She was killed, unintentionally, by Xander. Her spirit eventually contacts Helen from the merpeople's version of the spirit world when her body has been grave-robbed. Her ghost later instructs Cami and those on Ryn's side to help Ryn fight Tia. Rena Owen as Helen Hawkins, an eccentric woman who seems to know much more about the merfolk than she claims. It is revealed that she is descended from merfolk and shares ancestry with Ben and the other Pownalls. She eventually learns that she has a long-lost relative from the Marzdan family, most of whom are known as hybrids. She discovers that her mother Daphne was one of the merpeople/human hybrids who was promised to fellow hybrid Johnathon Rooney, but had chosen Helen's human father instead. This resulted in the death of Mr. Hawkins, a few weeks before Helen was born. She is eventually contacted by the spirit of her merman love Sarge and, later, Donna's. It is later revealed that she is, in fact, the great-granddaughter of the half mermaid/human daughter of Charles Pownall and his mermaid lover, from her mother's side. Tiffany Lonsdale as Tia (season 3), a new mermaid from another colony/tribe of the northern seas around Bristol Cove, Washington. The human locals refer to her as a "sea monster". Her intent on arriving on land is to coerce all other merpeople tribes and colonies to join her in putting an end to humans or perish by her wrath. She choose her name from Tiamat, Water Deity of the Seas. In the past, Tia was caught by humans while she was pregnant and she lost her unborn child as a result of how she was treated. As of "Survivor" and "Life and Death," she has since gained leadership of her own colony and is now bent on unifying all fellow merpeople colonies/tribes to eradicate humanity. To symbolize her higher status as the alpha female, she has orange markings on her tail and chest. She learns of Ryn's infant daughter Hope from Hunter, who she threatens with death if she does not join her and her colony. According to Helen, she is a tyrant. During the final battle, Tia is killed by Ryn causing the rest of Tia's followers to stop fighting and acknowledge Ryn as their new leader.
