Five Year Plan follows a group of three friends, Sarah being the main character. Each scene meets the group five years on from the last scene. We see two of the characters, Hannah and Roisin, mature and move on with their lives. We see Sarah stay the same, and the audience watches her turn from the ‘queen bee’ of the group to somebody immature and selfish, with an unhealthy relationship with alcohol.
The main theme the play explores is addiction- is someone an addict if they are functional? At what point do we stop calling someone a party girl and start calling them an addict? At what point do friends have to walk away so that the addict can save themselves?
