BAKER CITY — Abby Dennis can’t say anything about “The Clone People.”

Well, she could explain the plot — but then audiences wouldn’t be surprised by the twists and turns for this play staged by Eastern Oregon Regional Theatre just in time for Halloween.

“Literally, we can tell you nothing,” Dennis, the director, said with a grin.

Indeed, even the synopsis on the back of the script gives away too many hints.

“Everything about this is a spoiler,” she said.

Her cast agrees, although, they offer a few tidbits for audiences.

“It’s a thriller, a mind bender,” said Chris Lilley.

Addison Collard describes the setting — vaguely.

“1960s, southern California,” he said.

With the essence of “The Twilight Zone,” the cast of nine say this play is perfect for the spooky season that is October.

“There are deaths, but we can’t tell you who,” Dennis said. “Might be good guys, might be bad guys.”

EORT presents “The Clone People” over two weekends: Oct. 18-20 and Oct. 25-27. Performances are at 6 p.m. Friday and Saturday, and 3 p.m. Sunday, at the theater, 2101 Main St. Tickets are $13 adults, $11 members and $8 students. On opening night, Oct. 18, adult tickets are $11.

The plot, kind of

Audiences will know a few things once they peruse the program.

Addison Collard and Elisabeth Munsell play the main characters of Jay Westcott and his wife, Nessa Paxton. Both are successful movie actors.

But while filming on location, Nessa is hit on the head and drives — at high speeds — to their home in Beverly Hills. Hysterical, she tells her husband her name is Polly Ackerman, a girl who vanished before they got married.

Questioning her claim, and despite her protests, Jay allows the studio doctor (played by Daniel Lutz), to provide medical help.

But something isn’t quite right, and Jay soon suspects his wife is telling the truth and fears something is amiss at the studio.

The program ends with this: “For an evening of plausible nightmare, suspense and breathtaking terror with a shocking surprise ending, this show can’t be excelled.”

In addition to Collard, Munsell and Lutz, the cast features Payton Peppers as a newspaper reporter and Tina Ota as the Westcott’s nosy neighbor. Paul McNeil plays the head of the motion picture studio along with Rogue Groth, who is his assistant. Sue Samet plays Nessa’s personal secretary and Chris Lilley is Addie, the Westcott’s housekeeper.

In addition to directing, Dennis also designed the set along with Lauren Chaney. Reed Wagstaff is in charge of lights and sound.

Next up

After the psychological thriller of “The Clone People” wraps up, EORT will turn to a different season with “A Laura Ingalls Wilder Christmas” Dec. 6-8 and Dec. 13-15.
