  We report the results from an \asca observation of the QSO PKS 2149-306
(z=2.345). We detect an emission line centered at $\sim 17$ keV in the quasar
frame. Line emission at this energy has not been observed in any other active
galaxy or quasar to date. We present evidence rejecting the possibility that
this line is the result of instrumental artifacts, or a serendipitous source.
The most likely explanation is blueshifted Fe-K emission (the EW is 300+/-200
eV, QSO frame). Bulk velocities of the order of 0.75c are implied by the data.
We show that Fe-K line photons originating in an accretion disk and
Compton-scattering off a leptonic can account for the emission line. Curiously,
if the emission-line feature recently discovered in another quasar PKS
0637$-$752, $z=0.654$, is blueshifted Ovii, the Doppler factor is the same
(~2.7) for both.
