Nicky and Morgan are adult siblings who are utterly ill-equipped for real-world challenges. When their grandmother requires expensive medical treatment, they are pushed to the brink and decide to take a desperate risk: stealing a high-value piece of jewelry. However, their heist ends in disaster when they catch the attention of dangerous criminals. Now victims of ruthless blackmail, the siblings are forced into a dark criminal underworld, compelled to carry out increasingly lethal orders to stay alive.
