English Series to Watch Out For
But, before we get into the list of the New Series to be released this month, let us talk about a couple of years-old American political thriller, which is coming back for the third season. We cannot wait to see where this contemporary geopolitical tale is going to go.
The Diplomat (Season 3/USA)
In Season 3 of The Diplomat, Kate has just accused Vice President Grace Penn (Allison Janney) of hatching a terrorist plot and admitted she’s after the VP’s job. But now the president is dead, Kate’s husband Hal (Rufus Sewell) may have inadvertently killed him, and Grace Penn is the leader of the free world. None of this slows Hal’s campaign to land Kate the vice presidency. Kate steps into a role she never wanted, with a freedom she never expected, an increasingly complicated friendship with Foreign Secretary Austin Dennison (David Gyasi), and an unnerving bond with First Gentleman Todd Penn (Whitford).
