  Motivated by the recent discovery of the first hidden charm pentaquark state
with strangeness $P_{cs}(4459)$ by the LHCb Collaboration, we study the likely
existence of a three-body $\Sigma_{c}\bar{D}\bar{K}$ bound state, which shares
the same minimal quark content as $P_{cs}(4459)$. The $\Sigma_{c}\bar{D}$ and
$DK$ interactions are determined by reproducing $P_c(4312)$ and
$D_{s0}^*(2317)$ as $\Sigma_c\bar{D}$ and $\bar{D}\bar{K}$ molecules,
respectively, while the $\Sigma_c\bar{K}$ interaction is constrained by chiral
effective theory. We indeed find a three-body bound state by solving the
Schr\"odinger equation using the Gaussian Expansion Method, which can be viewed
as an excited hidden charm pentaquark state with strangeness, $P_{cs}^*(4739)$,
with $I(J^P)=1(1/2^+)$ and a binding energy of $77.8^{+25}_{-10.3}$ MeV. We
further study its strong decays via triangle diagrams and show that its partial
decay widths into $D\Xi_c'$ and $D_s^*\Sigma_c$ are of a few ten's MeV, with
the former being dominant.
