Jolt

Jolt: Directed by Tanya Wexler. With Kate Beckinsale, Jai Courtney, Stanley Tucci, Bobby Cannavale. A bouncer with a slightly murderous anger-management problem that she controls with the help of an electrode-lined vest she uses to shock herself back to normalcy whenever she gets homicidal. After the first guy she's ever fallen for is murdered, she goes on a revenge-fueled rampage to find the killer while the cops pursue her as their chief suspect.
