It stars Ross Noble, Tommy Knight and Gemma-Leah Devereux, with Shane Murray Corcoran, Thomas Kane Byrne, Eoghan McQuinn, Roisin Barron, Hugh Mulhern, John McDonnell, Tommy Cullen, Lorna Dempsey, Jemma Curran, and Ryan Burke in supporting roles.

[4] The plot concerns a young man dressed as a birthday clown returning from the dead to exact revenge upon a boy and a group of children/teenagers who contributed to his death.

Tommy visits Stitches' grave to put a squeaky flower on top, only to find a group of clowns entering an abandoned building.

The Motley warns Tommy that a clown who dies without finishing the party will never rest in peace, and a joke is not as funny the second time.

He is still haunted by the memory of his past birthday, and begins to have frightening hallucinations, such as a teacher turning into a clown and ripping off Vinnie's genitals before tying them to a party balloon.

As the guests, including Tommy's childhood crush Kate, arrive for the party, Stitches comes back to life and leaves his grave.

Meanwhile, Paul is attacked by Stitches, who rips off his ear and one of his arms and pulls a live rabbit out of his throat before kicking his head off.

Kate awakens and throws a knife at Stitches, while Tommy deduces a manner in which to defeat the clown; to kill him, they must destroy the egg he kept in his van.

McMahon began working on Stitches after receiving a €600,000 grant from the Irish Film Board, also utilizing funding from MEDIA Europe.

The film's soundtrack also features the 1986 song "(I Just) Died in Your Arms" by the English rock band Cutting Crew.

The party scene also features the song "Funk Epidemic", written by Danny Groenland, Conor Doherty and Ken McCabe and performed by Irish group Mob Fandango.

[9] It received a limited theatrical release in the U.S. under the distributor Dark Sky Films, and in Japan under Shochiku.

[14] Dread Central in particular praised the film's kill scenes, calling them "brilliant" and remarking that they were done "with such a rigorous sense of care and detail".

[15] Criticisms for the movie revolved around the film being "an incredibly low budget production" and the plot being "nowhere near as fun as it sounds on paper".

[14][16] Screen Daily commented that the "horror stuff is obvious, but staged with showstopping flair and buckets of blood".
