The extremely organized Lizzie Thomas (Jodhi May) is indispensable to her boss, Paul Reynolds (Damian Lewis), who, for all his brilliant ideas, would be miserably lost without her. But will his maverick style eventually tear them apart? Following the pair's 20-year working relationship from the earliest days of Thatcherism to the burst of the dot-com bubble, this thought-provoking drama paints a portrait of Britain's not-so-distant past.
