Alison left South Africa to pursue a scholarship at university in Texas and subsequently settled there. Now her life is shattered, not only by her husband's infidelity, but by a fall that leaves her wheelchair-bound. Feeling incapable of caring for her young children, she appeals to her half-sister, Bridget, for help. Raising families on different continents, the sisters have drifted apart.

Bridget abandons her own holiday to travel to Dallas. Initially, mundane activities become daily battlegrounds for both women. Bridget battles with being housekeeper, nurse and surrogate mother in her sister's home. And Alison resists the support both Bridget and her physical therapist offer as she struggles with the possibility that her once athletic body, now frightening unresponsive, may make her permanently dependent on others.

Will happier memories and the strong bond they once shared be enough to overcome yet another challenge?
