In Pendleton, a city steeped in history and old traumas, the flicker of a dark mist brings forth echoes of a terrifying past. When children begin to disappear, Marco Oliveira, a detective haunted by traumas from his own childhood, returns to his hometown at the sheriff's invitation. Alongside Isabela Santos, a survivor marked by family secrets and pain, and Tomás, a loyal friend and strategist, they delve into an investigation that uncovers the sinister presence of a cult known as "The Children of the Night."

Led by Lúcia, a charismatic and manipulative figure, the cult is dedicated to dark rituals aimed at invoking an ancestral entity through sacrifices. Lúcia's motivations go beyond mere power; she believes she can bring back lost souls, including her own family, by sacrificing innocents in the name of a "greater good." However, her actions conceal a selfishness that leaves a trail of pain and despair.

As they unveil the secrets of the cult, Marco and his friends discover that the missing children are not just victims; they are part of a larger plan, a rite that seeks not only recognition but also the ability to dominate not just Pendleton, but the very fabric of reality itself. The information gathered reveals that, to prevent the final ritual, they must find an ancient relic that can seal the cult once and for all.

As tensions rise and disappearances become more frequent, twists and turns arise. Miguel, Isabela's twin brother whom they believed lost, returns as an undercover agent in the cult, only to be protected by the cultists themselves. This revelation calls his loyalty into question and casts doubt on the trust the group had built.

With the full moon approaching, the struggle transforms into a crucial battle between light and darkness, where secrets of friendship and betrayal entwine. Marco must confront not only the cult but also his own internal demons. He realizes that true strength lies in truth and unity and that the greatest sacrifice may be the vulnerability he has been reluctant to accept.

"The Children of the Night" is a gripping tale of mystery and terror that investigates the limits of sacrifice and the echoes of the past, prompting the reader to question: how far would you go to protect those you love? The fate of Pendleton now rests in the hands of its heroes as they fight against the shadows that threaten to encircle them, bringing not only their fears but also the realities hidden beneath the surface of the town. The battle for the soul of the community is just beginning, and light will become the ultimate weapon for those brave enough to wield it.
