As the son and daughter of a mysterious and powerful serial killer, Helstrom follows Daimon and Ana Helstrom, and their complicated dynamic, as they track down the worst of humanity — each with their own attitude and skills.
In Portland, Oregon, Dr. Louise Hastings types on her computer when suddenly it starts typing "NO MERCY", causing her to call for a lockdown. Later, Sister Gabriella Rosetti meets with Daimon Helstrom to help a family who believe their son is possessed. Upon going to his room, Archer Cavallo starts speaking Latin, but Helstrom easily proves that he is faking which angers Cavallo. The child lunges at Helstrom but is surrounded by a ring of fire set off by Helstrom. Meanwhile, Ana Helstrom walks with Edward Tate and uses her powers to see visions of him murdering people. She kills him in retaliation.
Daimon gets a call from Hastings telling him that the patient is causing trouble. He goes to meet the patient at the mental hospital, which is his mother, Victoria Helstrom. He tries to talk to Victoria, but there is a demon inside of her named, Kthara, who taunts him back. Ana gets a call from Caretaker and looks through a casket that has killed a man. She finds a skull. Later, Daimon prepares for a tattoo in hopes of covering a scar on his body. He calls his sister, Ana, asking to talk. Meanwhile, Alex Tilden enters his truck, but finds a bloody person in the seat. The person then attacks him.
Ana meets Daimon at the asylum and they try to find a way to get Kthara out of their mother. Daimon also pushes to expand their relationship to actually acting like siblings. Ana gets close to Victoria, but the demon slaps her. Ana grins and says that it's the mother she remembers. Rosetti asks how they have powers, Ana says that it comes from their father. Ana's best friend, Chris Yen, finds the skull and hears it calling to him, but is interrupted by Caretaker. Later, he is swayed by the power and lets the skull bite his arm.
Daimon and Rosetti get a call about Tilden's truck accident. They arrive and Daimon realizes that Tilden is marked. He explains that only the strongest demons have the ability to mark their hosts. The demon, Magoth, uses a young victim to taunt the two. He then mentions Ana, which gets Daimon angry, so Magoth sets off a fire around them. Meanwhile, Ana uses memories to wake up Victoria without the demon for a short time. However, this is just Kthara taunting her. Daimon puts his hand on Tilden, eradicating Magoth, but not before the demon says that a worse one is out there. Another demon, Basar, opens up his rib cage and devours a victim at a public restroom.
Afterward, Magoth and Basar realize Daimon is coming. They decide to get the woman. Daimon later calls Ana and asks what she did to wake their mother as she hasn't been this lucid in years. Ana is then approached by Henry, Caretaker, who tells her that he found out her father, Marduk, is alive. She meets with Daimon at the asylum and see their mother. Theit mother warns them of Marduck's return and says he always finds his victims eventually. Kthara then awakes and remarks on how Victoria is a fighter.
The two then meet with Rosetti who tells them that she researched their father and found out that Ana wasn't the only survivor. There is a woman named Zoe Richards who also survived their father, but her family is private about the matter. Hastings has lung cancer and hides the medication from Henry. The siblings and Rosetti arrive at Richards' house, but believe Richards' story about the experience was fake. Meanwhile, a supernatural force tells a patient to kill Caretaker, which he attempts to do. Cartaker is able to get away and finds the medicine bottle in the process.
Ana decides to go out to get the truth from Richards. Rosetti and Daimon go to find her which leads to Rosetti going into the cellar alone. There she finds a woman with a half burned face claiming to be the real Richards as she pours gas on the ground. As it turns out, her twin sister, Aubree Richards was posing as Zoe. She then lights the flame, but is saved by Daimon. She says she just wants the pain to stop. Ana is led by a guilt ridden Aubree to their father. Aubree did this out of guilt for not helping her sister. Marduk, in a possessed body, attacks Ana and eventually kills Aubree before getting away.
Looking for better options, the siblings go to the facility in San Francisco to visit Yen, but find a dead man named Cameron Tate, and the skull is gone. Knowing it was Yen's doing, Daimon tries to call the police, but is stopped by Ana. Yen eventually finds himself underground in a pit of spiders. Daimon returns home to find Magoth in his living room offering a deal. Ana for their mother. Daimon refuses which causes an outburst from the demon, but is stopped by Daimon as well as Ana, who just arrived. Meanwhile, Victoria screams in pain as Yen is a floor under her, with the skull affecting her.
