A man and a woman walk into a restaurant. The woman hopes they will order the best wine on the menu. Instead, her husband tells her he is having an affair with a woman called Maggie. When her chest starts to ache, the woman goes to a doctor who tells her the pain in her breast isn't just heartbreak - but - cancer. She decides to call the tumour Maggie and begins to strike up a conversation with it.
In turns wildly funny and devastatingly tender, Maggie takes place during a pause -between divorce and marriage, sickness and health, the unknown and the status quo. In reaction to the unfolding chaos, the heartbroken woman creates 'A Guide to My Husband: A User's Manual' filled with a thousand facts for the real Maggie about the man they both love.
