Movie clips controlling backgrounds

i was wondering if it is possible for when you click on a movie clip/button, if it can activate another movie clip or timeline reaction in the timeline, like play current scene, frame 12.

that probably doesnt make much sense and is probably hard to grasp what im getting at, so… ill try set the scene.

i have 5 mc’s and a background. when you click on one of the mc’s the background should play and the mc you clicked on will also play.

any help would be appreciated.
