Ah! The weekly "how do I make a timeslice effect" question! I assume you have a reasonable budget or a lot of time - you're going to need it! you can either:
1. Shoot the scene as normal, but ensuring the static people remain absolutely still, to give the illusion of a frozen frame, like this:
2. Model the static elements (people, etc) in 3D, and animate the camera moving through them and comp your live action (moving) people on it.
3. Get hold of a few dozen digital cameras (you'll need one per frame of your shot, so assuming 25fps, you'll need 100 cameras for a 4-second shot), set them up precisely and trigger them to all take a shot at precisely the same time. This is how the timeslice effect is done properly.
4. Get someone else to do it, such as: http://www.timeslicefilms.com/
Sorry to be the bearer of bad news, but there really is no easy way of doing it. It's certainly not just an effect or plug-in. It's amazing how long this technique has survived - I remember first seeing it in a (Chemical Brothers?) music video around 1993 and being very impressed.
