A near-deserted island is transformed into a prison without bars, holding Singapore's most hardened gangsters. Three years later, a violent riot leaves the island in flames and prison guards murdered.
Late 1950s Singapore is plagued by the menace of secret-society gangs. To combat this rising threat, a new initiative is born: sending gangsters to a new open-air prison on Pulau Senang, where hard labor becomes a form of rehabilitation.
In Singapore's trial of the century, 59 men stand accused of rioting and murder at the open-air prison of Pulau Senang. Three years later, these detained secret-society mobsters burn the prison to the ground and slaughter 4 servicemen.
