No Room at the Inn
No Room at the Inn is a 1945 play by Joan Temple that became a 1948 film directed by Daniel Birt. Both play and film are presented in flashback mode and share the same subject matter - cruelty, neglect and mental and physical abuse meted out to evacuee children during World War II. Temple's attack on those who turn a blind eye to child abuse, be they public officials or private individuals, was considered frank and uncompromising in its time.
