Ed is up the duff, on an NHS maternity ward, already induced, waiting for a caesarean and the imminent birth of his daughter.
With his high-flying executive wife at his side, played by Anna Maxwell Martin, doing her best to remain sympathetic and patient, we follow Ed through the agony, the tears, the humiliation, the anxiety and the ecstasy of labour.
Birthday is written by Joe Penhall - adapted from his sell-out 2012 Royal Court play - and directed by the award-winning Roger Michell.
