A Simple Curve is a drama that follows a father, Jim (Michael Hogan), and his son, Caleb (Kris Lemche), as they work together in a furniture shop in Canada. While Caleb still has doubt about his life and career, everything seems to be running smoothly. That changes when a long-time friend of Jim, Matthew (Matt Craven), comes to town for a visit. Jim and Matthew spent a decent amount of time together when they were younger, but eventually took separate paths in life. While Jim still embodies the mindset of the hippie subculture, Matthew has gone on to become an affluent investor. Matthew comes to Caleb with a proposition. Caleb realizes their company's need for more work, so he signs a contract with Matthew to fashion a vast quantity of wooden chairs for a new lodge he is planning to open soon. They both agree it is best for everyone that Jim not be informed of this commission.
