Leo and Lily are a couple of sophisticated cons, who have become used to living the good life, so when one of their scams looks like it's in danger of turning belly up Leo turns to the local mobsters for help; but their co-operation doesn't come cheap and Leo finds himself increasingly stifled by his new business partners. There seems only one way out, the same way they got in, deceit. Circus has a good British cast, and is a slickly put together action thriller with more twists than I care to remember; That it doesn't quite work is a shame, but it's good fun nonetheless.
