Concerns
Violence
HighThe series prominently features violence as a core plot element, including murder and assassination. The protagonist, Ulises Albet, is implicated in a murder, and the story involves an assassin character who commits killings. There is also a backstory involving domestic violence and suicide.
Ulises Albet becomes the prime suspect in a murder during Mobile World Congress week. A character named Ramisa is a 'professional assassin' who 'committed murders in other European countries earlier' and 'kills Lucas' when he becomes a 'loose end.' Officer Alba, a police officer, works for the antagonist Damian Diskin and 'manipulates the crime scene' and is involved in 'Ramisa's death.' The backstory for Ulises mentions his 'sister's suicide due to bullying.' Damian Diskin's motivation stems from 'his abusive father assaulting his mother on a regular basis,' which led to his mother's death. The 'Day One' device itself is shown to make a test subject 'suddenly turn violent' through emotional manipulation.
Romance and Sexual Content
MediumAvailable plot summaries indicate the presence of a romantic relationship involving an assassin character. However, details regarding the explicitness or frequency of romantic and sexual content are limited in the provided information.
The assassin character, Ramisa, 'finds herself sincerely in love with her boyfriend, Lucas.' She plans to quit her profession and move with him, even considering admitting her crimes. When Lucas discovers her identity, she kills him, indicating a twisted and ultimately tragic romantic subplot.
Scary & Intense Content
MediumThe series is a tech-thriller involving a murder mystery, corporate conspiracy, and ethically dangerous technology, creating a consistently tense and suspenseful atmosphere. The manipulation of emotions by the 'Day One' device can also lead to frightening outcomes for characters.
The plot centers around a murder, a city under lockdown, and a global ethical threat from advanced technology, inherently building suspense. The 'Day One' device is capable of 'manipulat[ing] anyone's emotions' and made a 'test subject... suddenly turn violent.' This emotional manipulation creates psychological intensity and potentially disturbing scenarios, as seen when antagonist Diskin 'manipulates Rebeca's device as well, making her feel disoriented and scared of Ulises.'
Disrespect & Rebellion
MediumThe narrative features significant elements of rebellion against corporate power and established norms, as well as disregard for legal and ethical boundaries by various characters.
Ulises Albet is portrayed as a 'former tech prodigy turned anti-tech activist' who challenges the tech industry. He is seen as an 'uncomfortable figure' by the industry he once helped build. Damian Diskin, the CEO, manipulates the investigation and uses his technology to 'control and manipulate the users' emotions,' which is 'highly illegal and unethical,' demonstrating clear defiance of moral and legal authority. Officer Alba actively 'working on behalf of Diskin, letting the CEO completely control and manipulate the investigation' and concealing his involvement in a death, showcasing a serious disrespect for law enforcement integrity.
