Notorious hawk-eye sniper J.B. doesn't seem the type to keep a partner around, but little kitten Roy somehow seeped into his rock hard heart. Though they may be partners in bed, rarely are they partners in crime. Rather, J.B. watches (read: spies on) Roy from the shadows and protects him from any dangers... of other men trying to hit on his precious kitten! A meticulous veteran sniper and an eager, young fighter work with government agent friends (?!) and well to-do clients for rescue missions and job requests... Will everybody survive unscathed?...
