A sharply rendered and electric story about a couple drawn back to each other time and again, set from the perspective of everyone in their orbit except the couple themselves. When Clara and Seb first cross paths in a London square, it's the start of something exciting. Clara, an aspiring director stuck in an entry-level job, itches to pick up a camera. Seb, having floated between music, modeling, and now acting, struggles to find purpose in his work. Yet as random chance brings the two back together, time and time again, neither could predict that their magnetic connection is set to change their lives. But everyone else does. The spark between Clara and Seb is exactly what falling in love should look like: exhilarating, passionate, undeniable. The two become a whirlwind, their relationship enthralling everyone they come across.

But as the years go on and tensions flair, a last-ditch attempt to save their great romance ends with a gut-wrenching betrayal. Set over the course of two decades, Clara and Seb's love story is bigger than just themselves. Told from the eyes of their audience--friends and flatmates, rivals and lovers, strangers and confidants-- Main Characters is a sweeping portrait of all sides of Clara and Seb. Everyone has their version of events, but only they can decide how the story ends.
