Well, why did they join the circus in the first place? Maybe they all ran from some nasty villainl. It turns out, all their respective antagonists work essentially for the same evil organisation. They will be found sooner or later, so they have to somehow defeat this evil group.
They are currently away from their troupe, when they finally find them, they are all slaughtered. From the evidence (a few barely alive survivor's), they learn that bad guys came looking for them, but when they were not found / the Troupe didn't deliver them, the bad guys slaughtered the troupe.
Now the PC's are on their own, with a clue (the barely surviving troupe member either recognized one of the bad guys, or some insigne they were wearing, or a tattoo they all had. The race for revenge and survival is on!
