The Feast

Synopsis: An affluent family gathers at their lavish home in the Welsh mountains for a dinner party, hosting a local businessman and neighboring farmer to broker a business deal to mine the surrounding countryside. When a mysterious young woman arrives to be the family's waitress for the evening, they find their beliefs and values challenged, as her quiet yet disturbing presence begins to unravel their lives -- slowly, deliberately, and with the most terrifying of consequences.     Source: RottenTomatoes.com
