Altarboy: Cast, Episodes & Where to Watch

What is Altarboy about?

Altarboy is one of ReelShort's highest-profile queer dramas and one of the few boys' love titles to break into the mainstream of American vertical drama. Released in late August 2026, it passed 16 million views on its ReelShort page within weeks and reached number 32 on the Vertical Charts ranking. It is a slow-burn forbidden romance, but it is also a story about rejection, faith and who gets to decide what love is allowed.

Theo Martin is 18 and has just come out to his family. It goes about as badly as it can. Within a day his father has thrown him out, and instead of simply leaving him on the street, he drops Theo at Sacred Heart, a strict Catholic church, to be cured. For Theo, it is abandonment wrapped in religion, and he has no intention of staying.

He does not get far. Trying to leave town, Theo is cornered in a dark alley by a group of homophobic attackers, and the person who pulls him out of it is the last one he expected: Father Alexander, the church's new priest. Alexander is young, striking and, as far as Theo can tell, an arrogant jerk. He is also in a delicate position, because his standing at Sacred Heart depends on the goodwill of Theo's father.

So Alexander takes Theo on, reluctantly, as his personal altar boy. The arrangement satisfies the father and keeps Theo under a roof, but it does nothing for the friction between them. Theo pushes every boundary he can find, Alexander answers with discipline, and both of them start to notice that the needling has a charge to it that neither wants to name.

ReelShort describes what follows as a game of temptation that becomes a slow-burn obsession neither of them can pray away, and as the game turns real, both men risk losing everything. The first act sets up the stakes clearly: a young man rejected for who he is, a priest bound by vows, and a church community watching both of them. Written by Taylor Thompson, Altarboy is a live-action ReelShort original with an American cast, and its 63 episodes take the forbidden-romance setup seriously rather than playing it only for shock.

Altarboy cast

Main characters

Theo Martin

An 18-year-old who is thrown out by his family after coming out and left at Sacred Heart to be cured. He is defiant, funny and wounded underneath it, and he uses provocation as armor. Declan Clifford plays him.

Father Alexander

The new priest at Sacred Heart, young, commanding and quick to punish. He takes Theo on as his altar boy partly out of duty and partly because his position depends on Theo's father. Cayman Cardiff plays him.

Matthew Martin

Theo's father, who rejects his son for being gay and hands him over to the church. His influence over Sacred Heart is part of what keeps Theo and Alexander bound together. Michael Heymann plays him.

Sister Marlene

One of the nuns at Sacred Heart, part of the watchful church community surrounding Theo and Alexander. Danielle Steele plays her.

Mabel

A member of Theo's new world at Sacred Heart, played by Bella Caspersen. The series keeps several supporting characters in the background early on as the central relationship takes shape.

Why people are watching Altarboy

Altarboy offers something vertical drama rarely does: a queer love story at the center of the frame, with a real budget, a credited cast and a mainstream audience. For viewers who have spent years watching the same billionaire and werewolf plots with straight couples, it is a welcome change, and its numbers show how many people were waiting for it.

The chemistry is the draw. Declan Clifford gives Theo a mix of bravado and hurt that keeps him sympathetic even at his most provoking, and Cayman Cardiff plays Alexander as a man holding himself very tightly together. Their scenes crackle with the enemies-to-lovers friction ReelShort tags the series for.

It does not ignore the hard parts. The story opens with family rejection, an attempt to send a gay teenager to be cured and a homophobic attack, and it treats those as real harm rather than background color. Faith is part of the conflict, not a punchline. Some viewers will find that heavy, and the forbidden relationship with a priest is deliberately provocative.

Content note: ReelShort labels the series for all ages, not adults only, but it deals with conversion therapy, homophobic violence, religious guilt and sexual tension, and it is clearly made for an adult audience. Theo is 18 from the first episode. At 63 episodes, it is a two-to-three-hour slow burn.

Tropes and themes

Forbidden romance is the core of the story. A priest's vows, a church community that is always watching and a family that has rejected Theo all stand between the two leads, so every step closer carries a cost.

Enemies to lovers shapes the relationship. Theo and Alexander begin with open hostility, teasing on one side and punishment on the other, and the slow shift from antagonism to attraction is what keeps viewers swiping.

Family drama provides the wound. Theo's father throwing him out and handing him to the church is the event that sets everything in motion, and the father's continuing influence keeps the past from staying in the past.

Boys' love, often shortened to BL, is the broader genre label fans use for romances between two men. Altarboy borrows BL's slow-burn structure and intense emotional focus while setting it in an American Catholic parish.

How to watch Altarboy legally

Altarboy is a ReelShort original, so the official ways to watch are the ReelShort app for iPhone and Android and the ReelShort website at reelshort.com. Search for Altarboy as one word, and look for the 63-episode series with Declan Clifford and Cayman Cardiff. Do not confuse it with the 2021 film Altar Boy or other unrelated titles with similar names.

ReelShort is free to start. When we checked in October 2026, the series page marked episode 10 as the first premium episode, so episodes 1 through 9 are free. The trailer is listed as episode zero and is not counted in the 63. After that you unlock episodes with coins, earn bonus coins through daily check-ins and ads, or buy a subscription that opens the whole catalog for a set period. Prices and promotions differ between iOS, Android and the web, so check the current offers before you pay.

ReelShort tags Altarboy as LGBTQ and labels it for all ages rather than adults only. Even so, the themes are mature, and parents should know it involves conversion therapy, a homophobic attack and a romance between an 18-year-old and a priest.

Full-movie uploads on YouTube, Dailymotion and Facebook are unauthorized re-uploads, often cropped, missing episodes or wrapped in misleading links. They do not support the cast and crew. ReelShort's official social accounts post trailers and clips if you want a preview first.

Tip: watch in portrait mode with autoplay on. Altarboy is a slow burn, so it rewards longer sittings where the small shifts between Theo and Alexander can build from one episode to the next instead of being broken up over several days.
