A Netflix original, "Gunpowder Milkshake" follows a 27-year-old hit-woman working for a crime organisation, the Firm. All Sam knows is how to be an assassin, and the Firm is family — they were the ones who picked up the pieces after her mother left Sam when she was only 12 years old. But when a dangerous mission goes rogue, she must choose sides: the Firm or her helpless victim — an 8-year-old girl. She reaches out to the only person she knows who will know what to do: her mother. Will Sam be able to let bygones be bygones?
