In a rowdy little corner of Belfast, hapless young father Jimbo Reagan is having an unlucky week. Indebted to big-time gangster Mad Dog Flynn for $5,000, Jimbo decides to knock over the local fish market, only to find out post-robbery that it's a front for Mad Dog's illegal operations! On the lam with nowhere to turn, Jimbo holes up in a local antique shop and things go from bad to worse when he unwittingly takes five hostages. Shop manager Joe Maguire is one of these wrong-place-wrong-time hostages, but the situation proves to be serendipitous as Jimbo and Joe unearth encouraging discoveries about their intersecting pasts.
