British television viewers face a choice Sunday night as two highly anticipated crime dramas, BBC's "Vigil" and ITV's "Trigger Point," premiere their new seasons head-to-head at 9 p.m.

"Vigil" returns for its third season with Detective Chief Inspector Amy Silva (Suranne Jones) and Detective Sergeant Kirsten Longacre (Rose Leslie) investigating a murder at a remote Arctic research station. The case involves a covert British special forces mission and has the potential to trigger an international confrontation as global powers vie for control of Arctic resources amid a changing climate. The series creator, Tom Edge, noted that loyalty—to oneself, a partner, an institution, or a country—is a central theme across all seasons. "Vigil" seasons one and two are available for streaming on iPlayer.

Meanwhile, "Trigger Point" launches its fourth season, featuring bomb disposal expert Lana Washington (Vicky McClure) and her team of Explosive Ordnance Disposal (EOD) officers. This season is set to address Lana's past and presents the team with what executive producer Jed Mercurio described as the most dangerous bomb threat the UK has ever faced. The series aims to escalate the stakes by exploring the personal lives and relationships of the wider team, including fellow EXPOs Danny (Eric Shango) and Hass (Nabil Elouahabi), DS Helen Morgan (Natalie Simpson), DCI Batra (Maanuv Thiara), Commander Nia Quentin (Julie Graham), and civilian specialist Sonya Reeves (Kerry Godliman). "Trigger Point" seasons one to three can be streamed on ITVX.

Both "Vigil" and "Trigger Point" have garnered strong followings and critical acclaim, offering distinct viewing experiences: "Vigil" provides a slow-burn investigative mystery, while "Trigger Point" delivers high-octane drama. The new seasons will also air on Monday night, offering viewers a second opportunity to catch up if they miss the initial broadcast.
