Paul Meade and David Parnell's funny new play for Guna Nua theatre company exposes the indolence and skullduggery behind workaday office life.

Adam and Brian are mid-level paper-pushers in an unnamed company, who spend most of their time napping in the loo and pelting each other with screwed-up A4. When eager young Colm joins the team, they quickly teach him how to pad his working week so as not to give the impression of undue productivity.

Each has his own issues with women: Adam is a lady-killer currently getting it on with the boss's daughter (or so he says); Brian is the sincere guy struggling to provide for wife and kids, while Colm's girlfriend is overeager for them to live together.

A serious story lies beneath the comedy and, at least in this early stage of the show's run, quickly overshadows it. A promotion is in the offing for either Brian or Colm, and Adam - the boss's favoured golf partner - has to choose who gets the tap. As he deliberates, deeper entanglements and betrayals are revealed.

The script is well-observed and tightly written, but at the moment the rhythm and tone feel slightly off; there is a paranoid, Neil LaBute quality, when one senses that really it is aiming more for Nick Hornby lightness.

The show originated in last year's Dublin fringe festival and has that bare-bones, young company feel. The action proceeds in a series of short scenes punctuated with the tearing off of calendar pages; the actors shift the set (a labyrinth of portable office walls) themselves; and all take turns playing the boss by donning a Groucho mask and an exaggerated accent.

It isn't deep, but that's the point: it is quality light entertainment, and a fine showcase for the three terrific actors, Gerry McCann, Darren McHugh, and co-author Parnell.
