Protagonist Pictures has closed a U.K. deal for “April’s Daughter” with Alarm Pictures on the day of its British premiere.

Mexico’s Michel Franco wrote and directed the movie, which won the Un Certain Regard section at this year’s Cannes Film Festival and also screened at the festivals in Toronto and San Sebastian. It has its U.K. premiere Friday at the BFI London Film Festival.

The Spanish-language film from Franco, who made “After Lucia,” tells the story of 17-year-old Valeria (Ana Valeria Becerril), who is pregnant by her teenage boyfriend but hasn’t informed her absent mother, April (Emma Suarez). When her sister Clara goes behind her back and calls their mother, April arrives full of concern, support and tenderness but also, possibly, ulterior motives.

The deal with Alarm Pictures, which covers all rights in the U.K., was negotiated between Alex Mandell, Alarm’s managing director, and George Hamilton, Protagonist’s international sales manager. “Michel Franco is an exceptional filmmaker, and Alarm Pictures is proud to distribute and represent films that are purely about directorial talent,” Mandell said.

Protagonist CEO Dave Bishop added: “We have always had great experiences with Alarm, and Protagonist is excited to partner with them again to bring Michel Franco’s unique and original Cannes success to British audiences.”
