Yes, I know it's not Halloween, but I thought this would be a good idea for a story.
So there's a group of kids going trick or treating for Halloween (they're in their teens and they go really late). The guys in the group where the typical dudely costumes, and the girls where the typical sexy, girly ones...except for one guy and one girl. The girl decides to be Lisbeth Salander (if you don't know her, she's The Girl with the Dragon Tattoo), or Lara Croft (in one of the outfits that's not skimpy), or some other action heroine (not Wonder Woman though and nothing with a skirt). Then one guy decides to be a dude in distress. He decides to have his wrists tied with rope in front (not in back since he won't be able to get candy), but even so, he has a gag on. Maybe make it a lot of tape so it would be hard to get off, even with his wrists in front.
Anyway, the Lisbeth or Lara character (don't actually make her name Lisbeth though) and the dude in distress character decide to stay out after everyone's called it a night. It gets later and later and most houses have shut their lights off for the night, so they decide to go home. Lisbeth/Lara unties him and rips his gag off. However, some wackos are out.
The wackos jump them and start trying to kidnap them. The distressed dude, who in reality is quite like the character he was playing, immediately gets tied up and gagged. However, Lisbeth/Lara is tall and muscular, so she fights them. When the wackos realize they can't get her, they decide for just the dude in distress. They run off with him. So Lisbeth/Lara follows them in her car and comes to save the day. Please don't make her be any semblance of a damsel in distress. Like, don't have her tied up or anything.
That's just an idea I had. I don't know if anyone will like the idea or want to write it, but I just thought I'd try mentioning it.
