Rob Delaney and Sharon Horgan write and star in Catastrophe, a comedy following an Irish woman and an American man who make a bloody mess as they struggle to fall in love in London. Clumsy lust, instant pregnancy, and genuine disaster provide the foundation for this flaming hovel of a relationship. In a mess of events always in danger of slipping out of their grasp, Rob and Sharon must also learn to deal with her largely awful friend (Ashley Jensen); his eccentric Bostonian mother (Carrie Fisher); and attempt to navigate the choppy waters of their ever-more-complicating lives. Can Sharon, 'an extraordinarily good-smelling woman' and Rob, 'a sturdy love-maker' steer through the increasingly thorny situations they find themselves in and still find time for an emergency shag in a stairwell? Prepare to find out.
