But Detour playwright and director Devon Williamson's enjoyable comedy turns into pure farce as Irish killers Finn O'Reilly (played by Williamson himself) and his dim-witted son Donal (Glen Morris again) join the merry mayhem.
Complaining that practically a whole United Nations of professional murderers appears to have been brought in to deal to her, the resourceful Annie surprisingly succeeds in outsmarting them all.
Williamson has made a name for himself as a comedy writer - last year's production of The Old People Are Revolting played to full houses at Detour - and his latest offering brought plenty of laughter on Thursday's opening night.
A strong cast, which also includes Philippa Powell, playing Dane's none-too-bright sister Desiree, and the remarkable 84-year-old June Kontze as Grandma, are in fine form.
My Inlaws are Outlaws! runs until April 20.
