Nell Dart has succeeded in failing at school, in life and love. With nothing more to lose, she is sent to the 'last chance saloon', i.e. the ranch at the end of the world. A romantic adventure story, full of unfulfilled hopes, people and horses.

Mae Nell Dart wedi llwyddo unwaith eto. Llwyddo i fethu yn yr ysgol, mewn bywyd ac mewn cariad. Gyda dim byd ar ôl i'w golli, mae hi'n cael ei hanfon i'r Ransh Cyfle Olaf. Stori gariad ac antur, yn llawn ceffylau, pobl a gobeithion cyfle-olaf coll.
