Guilt is a new four-part drama from Scotland with riveting plot twists and a strong vein of black humour. Starring Mark Bonnar (Catastrophe, Line Of Duty) and Jamie Sives (Chernobyl, Game Of Thrones) as Max and Jake - two estranged brothers thrown together by tragedy and united by guilt.

Premiering on the new BBC Scotland channel followed by BBC Two, stylish contemporary drama Guilt is written by Neil Forsyth (Eric, Ernie And Me, Bob Servant), directed by Robert McKillop (Cleaning Up, Clique) and also stars Emun Elliott, Ruth Bradley, Siân Brooke, Ellie Haddington, Bill Paterson, Michael Nardone and Moyo Akandé.

In a residential street in Edinburgh, two disparate brothers, high-flying lawyer Max (Mark Bonnar) and record shop owner Jake (Jamie Sives) accidentally run down an old man, Walter, on their way home from a wedding. Uninsured and under the influence, Jake is persuaded by Max to cover up their deathly deed.

However, their hopes that the death will be passed off as natural causes are dashed when neighbours and relatives begin to suspect Walter’s death wasn’t as innocent as it seems. The brothers find their lives rapidly falling apart as their actions begin to catch up with them.

Their increasingly desperate attempts to conceal their guilt leads them further into a world where everyone seems to have a hidden agenda and they discover they can trust no-one - including each other.

• Episode one airs on BBC Scotland at 10pm on Thursday, 24 October and on BBC Two on Wednesday, 30 October at 9pm.
