Mix a Hitchcock masterpiece with a juicy spy novel, add a dash of Monty Python and you have The 39 Steps, a fast-paced whodunit packed with nonstop laughs, over 150 zany characters (played by a cast of 4), an on-stage plane crash, handcuffs, missing fingers and some good old-fashioned romance! SATE stages The 39 Steps as part of its Season of Mistaken Identity.
