Sonoko says she wants to start a girls' band, inspired by a movie she saw last night on the TV.
Since she says it ressembles her, Sonoko's in charge of the drums and Ran's put in charge of the bass.
Conan: "Ran - neechan's skilled at playing the piano, no?"
And so Masumi takes up the bass and Ran is placed in charge of the keyboard.
Sonoko yells that they take part in the city's entertainment contest and win it but... who'll be in charge of the guitar?
To try to solve that, they invite Azusa to take part because of her name tie.
Azusa argues back that she's got no experience in that and she's not a "girl" anymore.
Then a male customer who happened to be there and was a bandman suddenly exclaims:
"If ya put on a uniform and train to play the guitar then it'll be a piece of a cake!"
"I'll lend ya a guitar: piece of a cake, no? Try it out!"... Sonoko, who was fueled, is about to cry, even. (I think she finds the idea horrible.)
Amuro suddenly picks the guitar and lightly plays a song: the male customer shuts up. (Surprised at Amuro's level of skill, that is.)
Amuro then refuses the invitation from the girls saying that he doesn't want to stand out any more but
he says he will stick along to see their reharsals: and so the group head to a rental studio.
Masumi: "Hey, ya... Haven't you and I met... somewhere before?"
Amuro: "I think that... today's the first time we've met yet..."
The rental studio's full so the group wait for a room to be freed in the waiting area: about an hour passes.
Turns out that Sonoko's only experience with drums is a game named "Drum Master".
Masumi can at least play the Do-Re-Mi as she was taught by a friend of her brother yet
she doesn't remember having said that it was a man... Amuro...? (Maybe she's asking Amuro why he said that the friend was a man?)
Another girl band who was there is taking a break.
It is an all somewhere incronigous, and Someka (one of the members) lets out her annoyance in the other 3 members.
Hagie, another member, says she wants to have a light nap and so goes back to the studio.
They're about to have a memorial live in memory of a dead member, and Somehana is impertinent in that they must make it be a successs no matter what.
Yuiko (yet another member) keeps Someka's jacket because she wants to fix one of Someka's clothes' buttons yet
Someka has to re-do her guitar's strings so she stands her ground that she (Yuiko) must wake up Hagie.
Rumi (the 4th member) looks like she wants to rework a part of the song so she can't go wake up Hagie.
(In short: the member girls are named Someka, Hagie, Yuiko and Rumi. And there was a 5th member who's already dead).
Sonoko & co., in the meanwhile, want to use a Okino Yoko CD song as cover song yet they don't know who'll do the vocals.
Sonoko herself argues that she can't do the drums and the vocals at the same time and Masumi passes as well.
"Should we rather ring up Shinichi?", one (or both, not specified) of them suggest. But then Ran remembers that Shinichi's tone deaf.
A scream rings out from somewhere in the studio all of a sudden.
Conan, Amuro and Masumi rush over there but find Hagie dead with strangulation marks.
They check the security camera footage but about half of the screen is blocked by a phone with a selfie stick attached to it.
In these conditions they can't tell who did what.
A murder making use of a blind spot...?
