Paramount+ has dropped first look images of the worst stag do ever in Stags.

In the upcoming six-part drama series, My Mad Fat Diary’s Nico Mirallegro stars as Stu, who takes his close friends on a stag do in South America ahead of his wedding.

However, a week of drinking and fun turns to disaster when, instead of boarding a flight back to the UK, the stags are sent to a lawless prison island run by two warring siblings.

Quickly it becomes clear that the stags need to pick a side to have any chance of survival. Friendships are tested and life-long loyalty is sacrificed as Stu and his mates begin to question who will make it home alive.

Joining Mirallegro in the cast is This Country’s Charlie Cooper and SAS: Rogue Heroes’ Corin Silva as Stu’s close childhood friends, Ryan and Ant.

Newcomer Sophie Lenglinger (Druid O’Casey: Sean O’Casey’s Dublin Trilogy) and Paul Forman (Emily in Paris) play his university friends, Clem and Hugo, while Asim Chaudhry (People Just Do Nothing) rounds out the stags as Stu’s work mate, Greg.

Cavan Clerkin (The Last Kingdom) and Jojo Macari (Sex Education), are Stu’s in-laws John and Kai, whilst Paulina Gálvez (Desperation Road) and Oscar Foronda (Mallorca Files) are Selma and Branco Quispe, the two siblings who rule the prison Stu and his friends find themselves in.

Javier Godino (Sound of Freedom) joins the series as The Man.

Stags will debut exclusively on Paramount+ UK and Ireland in August.
