When Emily Pollard receives an invoice from HMRC for two million pounds, she asks her nephew, Michael and his friend, Jonathan, to work with a team of private detectives and find out what is going on at the mansion she lets to a company. Meanwhile, wise-cracking Jonathan, a university lecturer emerging from an acrimonious divorce, meets Lisa in a pub and she offers to pluck him from obscurity by adding him to the 'casual cast' of her PR video company, also introducing him to Mike's old girlfriend, Jenny. What with Lisa, barely-visible Cathy, the investigation and the sinister Inspector Cotting, Michael being attacked and left for dead and Jonathan accused of murder, it isn't long before both of the friends find themselves with more excitement than they'd bargained for. The machinations of Jon's ex-wife, Sara, only adds to the mix in this comical adventure.
