Mary and Martha

Wealthy American housewife Mary Morgan takes her bullied son George out of school for home education, including a trip to Southern Africa. Whilst in Mozambique, George is bitten by a mosquito which crawls through a hole in his net and dies of malaria. After his funeral at home, Mary feels a compulsion to return to Africa where she meets English woman Martha O'Connell, whose 24-year-old son Ben, a teacher with voluntary service overseas, has also died of malaria. Hilary Swank as Mary, Brenda Blethyn as Martha, and Sam Claflin as Ben join forces with Martha's father, James Woods, to testify before a Congressional subcommittee, raising awareness and funding for mosquito nets and malaria pills.
