Annie McHugh's lover and business partner is summoned to Arizona by his ex-wife, leaving Annie in charge of their Dublin-based private investigation agency. It's what she's wanted for a long time, but the reality is more frightening than she expected. The investigation into a suspect insurance claim made by a popular local character means that she's saddled with the enigmatic Sizemore (who might or might not be what he seems) from the Insurance Company. Add to this some dirty phone calls from a pervert who seems able to find her wherever she is and some difficult colleagues with problems of their own and it's easy to see that Annie has her work cut out.
