Mortal Sin

Mortal Sin is a bold, heartfelt, and sharply witty exploration of what it means to grow up different in an Ireland where the Church controls everything from the classroom to confession.

Through rapid-fire monologues, character switches and flashes of fantasy, Colm and Peggy paint a vivid portrait of their world, from Sunday mass to Audrey Hepburn.

Blending satire, nostalgia, and righteous teenage frustration, Mortal Sin is ultimately a celebration of friendship – a small but defiant stand against the silence and shame that shaped a generation. Colm and Peggy stick it to the man… well, Sister Assumpta anyway.

Mon-Sat at 1pm (doors open at 12.50pm)

Tickets: Low-price Mon/Tues €10, Wed/Thurs €12, Fri/Sat €15.
