This contemporary drama follows whip-smart doctor Mona Harcourt who lives in London with political lobbyist husband Guy. When a bomb goes off in London on the same day that her brother, Kareem, is abducted and murdered in Pakistan, Mona's charmed life is shaken to its core.

Depicting an epic 26th-century conflict between humanity and an alien threat known as the Covenant, the series weaves deeply drawn personal stories with action, adventure and a richly imagined vision of the future.
