Look, it's just a 3 hour tour and you expect us to believe they wound up on a remote island where nobody can find them? Never sell.
Ok, there's this other idea that's been percolating.
Rich dude scours all the police forces around the country to find the hottest female cops he can locate. He finds a blonde hottie, a sophisticated and savvy charmer and a brainy-but-hot nerd fantasy.
He starts a detective agency, hires some bozo to front it and then gets these exotic assignments to send his trio of girls out to work on.
I'm having trouble with the big boss's name. I was thinking Chuck, Chas.... something like that. And he'd call his detectives his Darlings. Or maybe Saints. Or something like that. Chuck's Darlings?
I think it would work because you've got hot girls in sexy locales and always in peril, but they find a way to win out. And they never find out who Chas is.
Or if THAT isn't up your alley?
This detective lives on the estate of this stuffy Brit who lets him drive an awesome Ferrari around the Hawaiian Islands. He's got a couple of douchebag pals, wears an Oakland A's hat and has a fierce moustache. I was going to call him Johnny Ammo. Or Marcus Cannon.
I got tons of them.
