We search for the charmless B^0 decay with final state particles p Lambdabar pi^- gamma using the full data sample that contains 772 * 10^6 B Bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^+ e^- collider. This decay is predicted to proceed predominantly via the b to s gamma radiative penguin process with a high energy photon. No significant signal is found. We set an upper limit of 6.5 * 10^-7 for the branching fraction of B^0 to p Lambdabar pi^- gamma at the 90% confidence level.
