Sam (KAREN GILLAN) was
only 12 years old when her mother Scarlet (LENA HEADEY), an elite
assassin, was forced to abandon her. Sam was raised by The Firm, the
ruthless crime syndicate her mother worked for. Now, 15 years later, Sam
has followed in her mother’s footsteps and grown into a fierce
hit-woman. She uses her “talents” to clean up The Firm’s most dangerous
messes. She’s as efficient as she is loyal.
But when a high-risk
job goes wrong, Sam must choose between serving The Firm and protecting
the life of an innocent 8-year-old girl - Emily (CHLOE COLEMAN). With a
target on her back, Sam has only one chance to survive: Reunite with her
mother and her lethal associates, The Librarians (MICHELLE YEOH, ANGELA
BASSETT and CARLA GUGINO).
These three
generations of women must now learn to trust each other, stand up to The
Firm and their army of henchmen, and raise hell against those who could
take everything from them.
