An unplanned pregnancy turns a weekend tryst into a serious commitment for a British woman and an American tourist. Season 1 sees the couple struggle as they begin to live together and meet each other's families. Rob Delaney and Sharon Horgan write and star in Catastrophe, a new six- part comedy that follows an American man and an Irish woman who make a bloody mess as they struggle to fall in love in London. Scorching chemistry, instant pregnancy, and genuine disaster provide the foundation for this flaming hovel of a relationship. Can Sharon, 'an extraordinarily good-smelling woman', and Rob, 'a sturdy love-maker', navigate the increasingly thorny situations they find themselves in and still find time for an emergency shag in a stairwell?
