At Ballycore Garda Station, Detective Inspector MAEVE HEALY (Aisling McLaughlin) rules the Gardai under her charge with an iron fist, while secretly holding a matriarchal fondness for a particular three. Through the eventful and sometimes very painful personal lives of Maeve's Guards, DIARMUID (Emmett J. Scanlan), MALACHY (Chris Patrick-Simpson), and AIDEN (Steven Aldridge), THE GUARDS explores the dark side of Dublin through the lad's warmth, humour, and absolute loyalty to each other. Being young, stubborn and impulsive, they're a lethal combination and Maeve has her hands full keeping them in line. In the coming months, they continue to clash with increasing severity when they are forced to confront certain disturbing events, not on the streets of Dublin, but in their own lives, and with tragic consequences.
