A small Muslim community in the prairies finally gets its own mosque–the problem is, it's in a church! Reverend Magee, who was tricked into the deal by the scheming Yasir, is suddenly very unpopular with his parishioners. The mosque's new Imam, Amaar Rashid arrives from the big city to smooth things over, but his easy charm and progressive ways do little to convince the locals that Muslims aren't simply a bunch of terrorists. A handshake deal between the new Imam and Reverend Magee ensures that Mercy's Muslims are here to stay

Baber, Mercy Mosque's conservative voice, decides a barrier must be erected to separate the men and women during prayer. Rayyan protests, convinced the community's liberal voices will prevail. But she has no idea what she's up against. A battle of the sexes ensues and Amaar's compromise ensures that no one will be happy. Meanwhile, Baber continues his long-standing and rather futile campaign to have Layla wear the hijab.

What better way to improve your image amongst suspicious townsfolk than to hold an open house at the Mercy Mosque? Amaar enlists Yasir to fix the room's decrepit electrical system before the big day arrives. Of course, the Muslims simply can't agree on what the open house should include. Long-winded history lectures? Islamic dating tips? Muslim munchies? In the end, the turnout is spectacular, but things come to sudden halt when an electrical fire has the guests convinced they're under attack.

Mercy's Muslim women protest co-ed swimming classes at the local pool. Mayor Popowicz refuses to change the rules, nervous at what voters will think if she's seen kowtowing to the Muslims. Meanwhile, Baber refuses to let Layla go out for Halloween, causing Amaar to suggest an Islamic version of the heathen holiday. In the end, the pool remains integrated, but Fatima dons an outrageous bathing suit to ensure she remains fully covered.

Marlon, a new white convert, has the entire mosque in a tizzy. Marlon's zealous embrace of Islam wins an immediate friend in Baber, but he soon alienates everyone by passing judgment on virtually everything the Muslims do. Meanwhile, Sarah, never too devout, decides it's time to become serious about Islam. But her passion soon wanes, even as Marlon's intensifies. Soon the entire mosque is cooking up hair-brained schemes to dampen Marlon's zeal.

When the Archdeacon announces he's coming to Mercy Anglican, Reverend Magee fears for the worst. With church attendance is way down, and the place just might get shut down. Because the Muslims realize that they have a stake in this as well, Yasir cooks up a scheme to have Muslims pose as Christians to help fill the seats. The archdeacon arrives early and quickly figures out the entire scheme, but he's delighted at the possibilities for the mosque's lucrative rent money.

Yasir's overbearing mother arrives from Lebanon with an exciting new proposition. Sarah is shocked to find that mother Hamoudi has plans for Yasir to take a second wife! Mayor Popowicz advises Sarah to fight back and take a second husband. Meanwhile, Reverend Magee ponders whether he should perform a gay marriage, amidst the protests of just about everyone. Yasir eventually solves his marital problems with a clever scheme that convinces his mother that one wife is enough.
