Both evening shows will include a full home-cooked meal of pork lions, mashed potatoes, noodles and green beans.
The matinee show on Saturday will include hors d'oeuvres and dessert.
Ticket prices for the evening shows are $18 per person, and the matinee show is $12 per person.
"Death of a Doornail" by Lee Mueller is a comedy with a parlor setting, including a maid and a butler in a wealthy home.
At one point during the show, guests will have a chance to vote for who they think the murderer is. Those who guess correctly will receive a prize after the play.
"Our cast is all local people, which makes it fun," Owner Laura Wells said. "They are just giving of their time to help us."
One actor who also performed in last year's show is Ted Jackson, former school board member.
"My wife and I have been on the adult support team for The Rock for a couple years now," he said. "We like that it gives students a place to go after school for entertainment."
Last year, the murder mystery dinner was set during a wedding reception. The Rock was decorated appropriately, and they even served wedding cake.
"I was the best man of the groom, and my name was Eddy," Jackson said. "I got to wear sunglasses so I got to hide in my character a little bit. The murderer was actually in the audience, which kind of threw everyone off."
Last year's mystery dinner was sold out each evening.
"It was a huge hit last year; everyone loved it," Wells said. "I think this is going to become our yearly fundraiser event."
The funds go directly to the ministry at The Rock, a non-profit organization existing directly on donations.
"We are rethinking the way ministry is done to make Jesus Christ relevant to our youth," Wells said. "The Rock is a place kids can hang out and be involved in our programs while being in a safe, Christian environment with good role models."
Jackson said as a parent of three girls, he thinks The Rock can keep parents from worrying.
"It reassures the parent that the child is at a safe place," he said. "They are having fun and being taken care of."
The Rock opens Monday, Sept. 12, and will run with the school year. On Mondays, it is open after school until 6 p.m. A senior high Bible study will take place at 6 p.m.
On Tuesdays and Thursdays, The Rock has an after-school elementary program for students in grades 4-6. They have snacks, games and a lesson.
Fridays are event nights for grades 6-12, from 7-10 p.m.
"We do special themed-nights," Wells said. "For instance, we might have a DJ come and have a dance, or we might have Chinese food one night or we might have a luau."
The Rock also provides a tutoring program.
Everything at The Rock is free, except for Friday nights, which have a $2 cover charge. They also have a coffee shop where youth can buy snacks or drinks.
"Adults aren't allowed at The Rock except for the volunteers," said Jackson, "and I think students like that too."
