Poor Sidney. His sister Jen bullies him into attending Amanda's engagement dinner - seeing the love of his life celebrate her betrothal to another man is the last thing the village vicar wants. He sinks a few too many drinks in a bid to make the evening more palatable, but it doesn't work - in fact, nobody at the event seems happy. Tensions rise between Amanda and Jen's old school friends, and then matters erupt when Jen's boyfriend Johnny (Ukweli Roach, Starlings) is accused of stealing Amanda's engagement ring. Later, the unfortunate chap is accused of murdering one of his fellow guests, and evidence at the scene of the crime seems to back up the theory. But Sidney isn't convinced - can he unmask the real killer?
