* ActionGirl: Trained martial artist [[https://www.imdb.com/name/nm3653808 Natalie Goldwin]] is listed as a stunt double and the actress Brianna Cohen has teased action scenes on her Instagram account, and there is more action than usual than a Lifetime movie.

''[[https://www.imdb.com/title/tt20872796/ My Sister's Serial Killer Boyfriend]]'' - originally titled ''Sister Obsession'' - is a MadeForTVMovie [[{{Thriller}} Mystery Thriller]] due to premiere on [[{{Creator/Lifetime}}the Lifetime Network]] on 8th January, 2023. The movie is directed by [[https://www.imdb.com/name/nm1876813 Danny J. Boyle]] (not to be confused with his [[Creator/DannyBoyle more famous namesake]]), and written by [[https://www.imdb.com/name/nm2100665 Andrea Shawcross]].

As the movie is currently unreleased, tropes are based primarily on this footage, [[https://www.mylifetime.com/movies/my-sisters-serial-killer-boyfriend promotional images]], and official plot synopses.

* ActionGirl: Trained martial artist [[https://www.imdb.com/name/nm3653808 Natalie Goldwin]] is listed as a stunt double and the actress Brianna Cohen has teased action scenes on her Instagram account, so expect more physical contact than usual for a Lifetime movie.
* DontGoInTheWoods: A blonde female - apparently Olivia - is seen running away from an armed Haden in the showreel, straight from an isolated country house into the woods.
* {{Flashback}}: Implied given younger versions of Maddie and Olivia are played by child actresses [=AnaSofia=] Bianchi and Zoe Mackenzie Smith respectively (according to IMDB). It's not clear whether this will be a happy or tragic past.
* EvilTeacher: Olivia's martial arts instructor Haden may well be a serial killer.

** In the showreel, a black-clad masked intruder takes a pair of scissors which are later used to [[spoiler:stab Kyle in the chest]].
** Lifetime's promotional image shows Olivia clutching a broken piece of wood, ready to defend herself.
* InTheHood: Haden generally wears an all-black hooded outfit when sneaking around. The showreel shows him acting suspiciously in a bedroom and office building.

* NervousWreck: Olivia is visibly fearful, seen sitting and cowering against a bedroom wall in the showreel. Lifetime's promotional image shows her hiding from a blood smeared Haden, so perhaps she has good reason.
* NeverOneMurder: A higher body count than usual for modern Lifetime flicks, with three named female victims on the credits and a further (male) victim in the showreel.
* OldDarkHouse: An isolated property surrounded by woodland features prominently in the showreel, with plenty of dark rooms for atmosphere.
* SacrificialLamb: Bella, Nicki and Sam are all credited on IMDB with the prefix Murder Victim, so expect these to be minor characters even if they get an on-screen death.
* SacrificialLion: Based on the showreel [[spoiler:Kyle]] has a meeting with Maddie in a cafeteria and is possibly assisting her with the investigation. That's until he's seen off by the killer in an office building.
* SerialKiller: Be careful if you're a blonde woman in this movie. That's most of the main female characters, except for the brunette Rachel.
* StalkerWithACrush: Haden takes a sinister interest in Olivia, and is seen [[spoiler:holding Maddie captive]] in the showreel.
* SuspiciousSkiMask: The killer - as seen in the showreel - wears a full black face mask with only eyes and mouth visible.
* WhiteShirtOfDeath: Haden is seen wearing a blood-covered white outfit in the promo image, stalking a terrified Olivia.

!!''My Sister's Serial Killer Boyfriend'' contains examples of:

* SacrificialLion: Based on the showreel [[spoiler:Kyle]] is an acquaintance of Olivia and gets some decent screen time, but is seen off by the killer after being attacked in an office building.
* SerialKiller: Be careful if you're a blonde woman in this movie. This applies to almost all main female characters, except for the brunette Rachel.
