I have an easy actionscripting question

i have an interactive cartoon in the works. It involves zombies and the viewer clicking things to find more detail in what they clicked. I have a problem however,

since there is a limited amount of time before the zombies get to the main character i need a way to view the detailed portions of the animation but it has to return to the point at which the user clicked the object to avoid the zombies from jumping back to the beginning of the animation.
i am aware that i can select which frame to return to the animation from a cut scene, but how do i make it define by the click of the user?

any help at all with this issue will be greatly appreciated.
