Clean Sweep Season 2 is yet to be announced by Sundance TV

The pressure builds on all fronts as Jason tries to close the case. Will Shelly be able survive as the pressure builds? The one option closed to her is to flee - she would never leave her children.

Shelly tries to change her fingerprints, while the investigation in London is developing new leads despite political pressure to close the case.  New witnesses give descriptions of the suspect that may point to Shelly.

The investigation continues to build steam in both countries, while Shelly continues to juggle her parenting and family responsibilities – problems with her husband and children that would stress anyone.  As Jason's partner Fiona grows suspicious of Shelly, we learn of the measures Shelly took to change her identity.

We learn of Shelly's dark history, as a teenager who was part of a drug ring in London 20 years earlier with Charlie Lynch, the man she shot.  When Lynch's true identity is uncovered, a UK officer, DSI Crichett, reopens an old murder case Shelly and Charlie were linked to.

Shelly's husband Jason, a Garda Detective, is delighted to be assigned to the case, with no sense where the trail may lead. While he and his co-worker, Fiona, focus on a sex worker, Shelly realizes she may have left evidence in the dead man's hotel room.

Shelly Mohan, a housewife and mother of three, makes an irreversible decision, and commits an unspeakable act, when a man from her distant past surfaces - she commits murder.
