A young couple, struggling to buy a first home, think their prayers are answered when a distant relative bequeaths them a vast country house. The catch? It's riddled with ghosts.

Alison - still recovering from her near-fatal accident - finds herself hounded by the ghostly gaggle, who now realise that she can both see and hear them. With Mike assuring her that these visions are exactly the sort of side effect her doctors warned her about, Alison tries to ignore their existence - a tactic which only exacerbates the problem, as the long-dead army captain puts the ghosts onto a war footing.

Meanwhile, Mike's attempts to turn the old house into a home leads to a DIY disaster, saddling Lady Button with an ill-suited roommate. And the ghosts are introduced to the internet, allowing Julian to learn about his questionable legacy.

It's Pat's 'passing day' and he prepares himself for his family's annual pilgrimage to the site of his demise. But, realising that Alison is a conduit between the dead and the living, he begs her to pass on a message from the other side - a plan complicated when Pat realises a shocking truth about his marriage. Meanwhile, Mike struggles to come to terms with his bathroom-based paranoia, and Kitty tries to find out where babies come from.

Desperate for cash, Mike and Alison rent the house to a film crew making a period drama - a move that pushes both Thomas and the old house's floorboards to breaking point.

Alison's attempt to win over their posh new neighbours with a swanky dinner party are thrown into chaos by Mary's woeful catering and Robin's desire to celebrate the lunar eclipse.

When Mike and Alison consider selling Button House to a hotel chain, the ghosts come up with some get-rich-quick schemes to help the cash-strapped couple.
