An Irish woman and an American man 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; his eccentric Bostonian mother; 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.
A new acquaintance becomes increasingly friendly with Rob, while Sharon dabbles in a new hobby.
Rob's newly religious sister Sidney visits from the US, and a child's accident at school reveals a surprising teacher-pupil rapport to Sharon.
Sharon and Rob decide to get on a fitness drive. When Sharon visits her less-than- sympathetic local GP it dawns on her she's not in the peak condition she imagined.
Rob is pretty unenthusiastic about the prospect of celebrating brother-in-law Fergal's 40th birthday. Sharon comes face to face with her mum's new man, while Fran and Chris drunkenly party with their new partners.
Sharon is unsettled by a strange moisture patch at school, while Rob's big boss visits London and takes a close interest in his career. Fran and Chris make a major decision.
