Asylum

Natasha Richardson is Stella, the beautiful, neglected wife of Max Raphael (Hugh Bonneville), the newly appointed Deputy Superintendent of a maximum-security psychiatric hospital outside of London. Soon after her arrival, Stella develops a curious attraction to Edgar Stark (Marton Csokas), an artist confined for the gruesome murder of his wife in a jealous rage. Secretly observed by the cunning Dr. Peter Cleave (Ian McKellen), Stella and Edgar begin a torrid affair. But as passions are ignited, so are suspicions, rage and jealousies, plunging the characters into a thrilling game of cat and mouse that builds to a shocking, fever-pitched conclusion.
