"How to Get to Heaven from Belfast," the new series from "Derry Girls" creator Lisa McGee, is set to arrive on Netflix on Thursday, February 12.

"Cracking this mystery will be deadly craic," Netflix UK & Ireland said on Thursday when it dropped the first trailer for "How to Get to Heaven from Belfast."

A synopsis for the new series says: "Clever, chaotic TV writer Saoirse, glamorous, stressed-out mother of three Robyn, and dependable, inhibited carer Dara have been a tight-knit group since school. Now in their late 30s, but still as close as ever, these three friends are about to embark on the most thrilling adventure of their lives.

"When an email arrives, telling them about the death of the estranged fourth member of their childhood gang, a series of eerie events at her wake set them on a dark, dangerous and hilarious odyssey through Ireland and beyond as each tries to piece together the truth of the past. 

"A show about friendship, memory and what happens when life doesn’t turn out quite like you’d expected."

Creator Lisa McGee told Netflix blog Tudum: “We got the gang back together — the creative team behind Derry Girls has reunited to bring you 'How to Get to Heaven from Belfast.'

“This is the show I’ve always wanted to make; a mash‑up of my two favorite genres, mystery and comedy. We want to keep you guessing and keep you laughing.

"I can’t wait for you to meet Saoirse, Robyn, and Dara, and go on this wild, weird adventure with them — an Irish odyssey  — full of twists, turns, and arguments about eyelash extensions.”

McGee said that she’s “in awe of this cast, their talent, timing, and chemistry," and praised Michael Lennox’s direction as “simply stunning.”

She added: “Netflix has been so incredibly supportive of our mad vision. Get ready to piece this puzzle together. And remember — a good friend keeps your secrets, but a great friend helps you bury them.”
