The cosmic gamma-ray burst event on March 5, 1979, is discussed, and the possibility that it may originate in a binary star system containing a neutron star is considered. It is shown that if the stellar wind from the companion star is enhanced suddenly, a great quantity of plasma piles up at the magnetopause of the neutron star and forms a high density accreting ring. When the mass of the plasma in the accreting ring exceeds critical values, the Kruskal-Schwarzschild instability causes the plasma in the ring to inject into the magnetosphere, and when the injecting plasma reaches the surface on magnetic poles of the neutron star, a gamma-ray and hard X-ray event occurs.
