It’s not easy being a security guard today, with mortal danger lurking around every corner. A public gathering such as a theater performance is a particularly seductive target for an attack. Which is why a security company has been hired – to make sure everyone stays safe. But is merely protecting ever enough, in a world where everything – even security – aspires to show business? Here, a small but successful security company, staffed with former actors, has been hired to protect a certain precious theater curtain – and behind it, whatever mystery it conceals. But things are about to get out of hand as the guards find themselves infiltrated by a rival security company composed of ex-ballet dancers, who are not only artistically more up to date, but also faster and cheaper, and who want to take over this important gig at any cost.
