Summer, 1936. The writer, Josephine Tey, joins her friends in the holiday village of Portmeirion to celebrate her fortieth birthday. Alfred Hitchcock and his wife, Alma Reville, are there to sign a deal to film Josephine's novel, A Shilling for Candles, and Hitchcock has one or two tricks up his sleeve to keep the holiday party entertained - and expose their deepest fears.
