Deadline said Friday that the action-comedy will start streaming June 23 on Amazon Prime Video.
The new movie follows Lindy (Beckinsale), a woman who experiences sporadic murderous impulses that can only be stopped when she shocks herself with a special device. The character seeks revenge after her first love is murdered.
"My character, Lindy, is someone who since childhood has had an impulse control problem whereby she has a very difficult time not acting out and behaving badly when under pressure," Beckinsale told Entertainment Weekly.
"As part of her therapy, she goes on a date and really gets on with the guy, and then he's murdered. She's understandably upset and pissed off and tries to figure out what's happened and gets into a lot of scraps!" she added.
Beckinsale had nothing but praise for her co-stars, especially Tucci, who plays Lindy's therapist.
"Stanley Tucci is an absolute jewel in the crown. There isn't a better person alive than Stanley Tucci, I will join the ranks of people who have said that," she said. "Yeah, it was just an absolute treat every day because you always had someone amazing."
Beckinsale is known for playing Selene in the Underworld movies.
