The Fool of Cavan: A Christmas Caper is a Nancy Drew-style mystery. Set in the 1960s in Millbrook, a church congregation is divided when props and costumes for the upcoming Christmas concert go missing. The Needlers, a band comprised of local young people, are accused of being the culprits. Tensions mount and The Needlers take to the streets of Millbrook to solve the mystery and clear their names. 
“Our off-season productions are fast becoming Millbrook favourites. I am so excited to share with our audiences, Lindy’s quirky and intriguing play.”" - Managing Artistic Director, Kim Blackwell.

Set in the roaring '20s, the stars of the silver screen are heading to Canada as Trenton, Ontario embarks on a quest to become Hollywood North. Sparks fly in this world premiere when small-town Ontario residents collide with the Hollywood elites. From Alex Poch-Goldin, the playwright who brought you The Right Road to Pontypool and The Bad Luck Bank Robbers, The Great Shadow is a raucous comedy, packed with romance and intrigue in the golden age of film.
“I love a cock-eyed optimist with a crazy dream.  I think in some ways that type of person started this theatre  (I am looking at you Robert Winslow!). And in Alex’s play we have just such a character, with the vision to see the potential benefits and possibilities of a Hollywood-style movie studio in Trenton, Ontario. I chose to develop and produce this play because I love the way that Alex pokes fun at both the locals in Trenton and even more the Hollywood types who find themselves in the hinterland of Canada. It is the best kind of 'fish out of water' story - the type of story Alex has explored so well for us in the past with both The Right Road to Pontypool and The Bad Luck Bank Robbers. It is a story of the dreamers and their dreams.  I like to think that each of us have a little bit of the dreamer in us.” - Managing Artistic Director, Kim Blackwell.

Wishful Seeing, based on the novel of the same name by Janet Kellough, published by Dundurn Press, tells the story of saddlebag preacher Thaddeus Lewis, who stumbles upon a murder mystery on the shores of Rice Lake in 1853. A historical thriller with a colourful cast of characters set against the backdrop of a rapidly growing pre-confederation Canada. Reminiscent of the popular CBC television series “Murdoch Mysteries,” this world premiere from Maja Ardal, the writer of the sell-out hit The Hero of Hunter Street, is sure to be a 4th Line classic. 
“When the book, on which the play is based, was given to me in the summer of 2016, we were in the midst of our 25th season.  I finally got around to reading it in late August and immediately thought that the novel would make for a super script.  It is an intriguing story of religious melancholia, obsessive and uncontrollable attraction and how delicate reputations can be easily destroyed in a small town.  I thought all three themes were unusual and not ones we normally explore in our plays. I think Maja has beautifully captured small town Ontario in the 1850s and she breaths life into the variety of people attempting to make their way in the new world. These people had to be hard because their lives were punishingly hard. In this play I constantly feel our ancestors all around us.  And I love a murder mystery in the style of Agatha Christie or PB James, this play is reminiscent of the works of these giants in the genre.” - Managing Artistic Director, Kim Blackwell.
