  We study the three body $N \bar{K} K$ system by using the fixed center
approximation to the Faddeev equations, taking the interaction between $N$ and
$\bar{K}$, $N$ and $K$, and $\bar{K}$ and $K$ from the chiral unitary approach.
Our results suggest that a $N\bar{K}K$ hadron state, with spin-parity
$J^P=1/2^+$, and mass around 1920 MeV, can be formed.
