When the light passes from a medium with a high index of refraction (low speed) to one with a lower index of refraction (higher speed) the beam is refracted at a greater angle than the normal interface. This leads to the fact that for a certain angle of finite incidence the angle of refraction reaches 90 degrees making it impossible for the beam to pass to the second medium. That leads to the beam experiencing a total internal refraction.
