Behind the faded grandeur of a seaside resort, the vulnerable and poor become prey for local predators.
Whilst working for a petty loan shark, Leighton is unwittingly chaperoned for the day by his older brother Cass, a gentle man with learning difficulties. Tasked with minding Cheryl, a debtor, Leighton leads the trio to a childhood haunt, the aquarium.
In the tranquility of blue, brothers share memories of their late mother and happier times. Doubting his role in Cheryl’s fate and reluctance as an enforcer, Leighton seeks a kinder resolution offering to clear the debt. But when the offer is refused, Leighton must bite back.
