Taking place on April 3, 1968, The Mountaintop is a gripping reimagining of events the night before the assassination of civil rights leader Dr. Martin Luther King, Jr. (Samuel L. Jackson), as he retires to Room 306 in the now famous Lorraine Motel in Memphis, after delivering his legendary "I've Been to the Mountaintop" speech to a massive church congregation.
When room service is delivered by a young woman (Angela Bassett), whose identity we puzzle over, King is forced to confront his past, as well as his legacy to his people.
