We report the measurement of the branching fraction and $CP$ asymmetry for the $\bar{ B}^{ 0}(B^{ 0})\to K^{ 0}_{ S}K^{ \mp}\pi^{ \pm}$ decay. The analysis is performed on a data sample of 711 $\rm{ fb}^{ -1}$ collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{ +}e^{ -}$ collider. We obtain a branching fraction of $(3.60\pm0.33\pm0.15)\times10^{ -6}$ and an $\mathcal{ A}_{ CP}$ of $(-8.5\pm8.9\pm0.2)\%$, where the first uncertainties are statistical and the second are systematic. Hints of peaking structures are also observed in the differential branching fraction as functions of Dalitz variables.
