In the run up to its world premiere at the Venice Film Festival, Elizabeth Lo (“Stray”)’s anticipated second feature documentary “Mistress Dispeller” has been boarded by The Party Film Sales.

The Paris-based company has acquired international sales rights to the movie and has unveiled a clip. AC Independent and Submarine Entertainment are handling North American sales.

“Mistress Dispeller” will bow in the Horizons section at Venice on Sept. 2 before having its North American premiere at Toronto.

“Mistress Dispeller” takes place in China, where a new industry has emerged devoted to helping couples stay married in the face of infidelity. Wang Zhenxi is part of this growing profession, a “mistress dispeller” who is hired to maintain the bonds of marriage — and break up affairs — by any means necessary.

The documentary follows a real, unfolding case of infidelity as Teacher Wang attempts to bring a couple back from the edge of crisis.
