Truth and Consequences

Alan has changed because he's injured his back. Pain has altered his appearance and made him glum, demanding and resentful. His wife Jane has to do everything for him - fetching, carrying, shopping, cooking, even dressing and undressing him. Sometimes she longs for escape.
Delia is a writer and researcher specialising in fairy tales - she is, in her own estimation, a 'Great Artist'. Her husband, Henry, manages her every need making certain Delia gets everything she desires including spectacular doses of adulation.
Can Delia coax Alan out of his grumpiness? Can Henry stop Jane feeling guilty? Can the two couples break out of their fixed roles?
