A Dog’s Breakfast (2007)

If you’ve never been good at anything in your life, why would murder be any different? Patrick (David Hewlett) has always had a somewhat combative relationship with his little sister Marilyn (Kate Hewlett), but when she brings home her new sci-fi soap star fianc� Ryan (Paul McGillion), it’s all out war. When Patrick fails to drive a wedge between the happy couple, he reaches for sharper instruments.
