The synopsis for season 1, episode 6 titled, “Sister Issues,” explains that Holly’s confidence will be swayed when her seemingly perfect sister arrives for a visit, so Nick uses a phony case in order to boost her confidence.
In the promotional trailer for “Sister Issues,” Holly is peering through a magnifying glass as she says, “I’m a detective with a serious job.” (Are her insecurities about her sister coming out?) Yep, she definitely looks like a serious detective. NOT! But that is what makes "Mystery Girls" funny. The viewers are in on the joke!
Holly and Charlie will show their bad girl side in this episode. Decked out in leather, the girls appear to go undercover as a couple of biker babes, and as always, when the case has a resolution, the girls exchange their high-fives with the phrase, “Mystery solved!”
Look closely. There is a corporately dressed blond woman sitting on a stool in the background of the biker bar. (Holly's sister?) When the girls take down the bad guy, she jumps out of the way as Holly says in a tough-girl voice, “That’s how we roll.”
It won’t be surprising if the show reveals that Holly's sister is just as insecure about Holly as Holly is of her.
“Mystery Girls” is a sitcom reuniting Tori Spelling and Jennie Garth, former co-stars of Fox’s “Beverly Hills, 90210,” as Holly Hamilton (Spelling) and Charlie Contour (Garth), two former TV show detective starlets from the 90’s brought back together by a real – life mystery. (Reuniting after their 90’s TV show – sound familiar?)
Charlie is a mother and housewife, while Holly is still a diva longing for her celebrity days. Both former co-stars reunite when Nick (Miguel Pinzon), a witness to a crime comes forward, but only wants to give his statement to the former ‘Mystery Girls’ stars. Charlie and Holly’s reunion brings about the formation of a real-life detective agency called “Mystery Girls,” with Nick, their super-fan, hired as their assistant.
With references to Shannen Doherty (Brenda from “Beverly Hills, 90210”) and The Peach Pit (Joe E. Tata, who played Nat, the owner of The Peach Pit on Fox’s “90210,” guest-starred on “Mystery Girls” episode 5), this show knows how to make fun of itself, while feeling like a former “Beverly Hills, 90210” reunion.
