In Alabama in the mid-1950s, black Rosa Pikes triggered an anti-racial discrimination protest because she refused to ride in the ghetto on a public bus. King mobilized local blacks to refuse to enter the city by bus. Hubby Goldberg plays the maid of Sissy Spasik's family, who walks nine kilometers to work every day to support the protest. When the white hostess found out about this, she tried to influence her businessman husband to take action to improve the black-and-white segregation, but she did not get a kind response, so she took the initiative to pick up black women who took part in the demonstration. Director Richard Pierce painstakingly managed the atmosphere of the times in southern towns to enhance the realism of this period of history, coupled with the equal performance of the two leading actresses, so that the film, which is relatively mediocre, still has a good viewing.
