It depends on the "impact parameter" (distance of closest approach) and to some extent on the spin of the Black Hole.
If the Black Hole is very massive, and the impact parameter is small, then the star can just be swallowed up.
If the Black Hole is not massive, it will be much smaller than the star and will "disrupt" the star, perhaps sending some of the material from the star away from the Black Hole --- this can be very bright.
