Two children who are both on the receiving end of unspeakable parental abuse eventually take different paths in life. The boy is unable to overcome his past. The girl fights through the memories to carve out a new life for herself. The difference between the two siblings comes down to a matter of conscience.

The focus of "No Brother of Mine" (a.k.a., "Lethal Obsession") is on the relationship of the siblings Drew and Nina Brampton. While Nina married to a doctor and has two beautiful children, Drew is obsessed with his sister and the memories of their traumatic past. Nina has forged a new identity and has not seen her brother in years. But he finally locates her, and Nina's world may be destroyed by his arrival.

Drew murders two innocent people during the action of the film. But the more repellent character turns out to be Nina's husband, Dr. Stuart St.-Clair. Stu is a philandering doctor, lying to his wife and making promises he cannot keep to his lover, an associate at the hospital named Miriam Jordan. At one pivotal moment in the film, Stu has the opportunity to at least save one life from the clutches of his psychopathic brother-in-law. But the spineless doctor tries to make a break for it, leaving poor Miriam at gun point with Drew.

Much of the action of the film is far-fetched to the virtual point of comedy. It was not believable that the smooth-talking Drew could evade the long arm of the law and use a phony charm to attract and begin romances with both the St.-Clair household maid, Isabelle, and Nina's co-worker, Karen.

But the film is still worth watching for the outstanding performance of the actress playing Nina, who created a multi-dimensional character that defines the essence of a survivor. Nina's father was an abusive drunk, and, as a little girl, she chose to set fire to the family home with him inside. While Drew was impacted by the event to become a killing machine in his fantastic self-image of avenger, Nina lived stoically in horror of the crime she had committed. Yet she possessed one salient quality that Drew could never fathom: Nina had a conscience.

One of the recommended films IMDb offered up for this movie, which I saw under the Lethal Obsession title, was Die A Little. It's an appropriate choice, because it reflects the feeling you get after having watched this film. A little bit of your life is gone forever. It's a cross between soft-core straight porn, a typical stalker movie, and an episode of Cheaters, with some freaky almost-sexual sibling love thrown in. And some remarkably bad acting, bad music, bad dialogue, bad costume and makeup, truly bad hair, and general badness all around. Anyone familiar with Canadian pay TV will be able to predict the logos that appear in the end credits. It's always depressing to know you paid twice for the film, once via taxation and again via your cable bill. Nevertheless, it's a better result than usual for that kind of funding. It actually gets a 6 from me, which shocks me more than anyone else, because there are some interesting parts of the story. But if there's a next time, it better be better than this.
