In the first of a series of increasingly uncomfortable encounters, Tasha & Jack's anniversary dinner is interrupted by Jen. When Tasha is awkwardly reminded of Jen's close ties to Jack's family, fear leads her to ask Jack to cut contact with Jen.

As Jen remains firmly in the peripheries of Jack and Tasha's family life, Tasha spirals into paranoia as she comes to believe that, rather than her husband, Jen is actually after her daughter. Her worst fears are realised when Emily disappears.

Desperate to get her daughter back, Tasha will do anything to get to the truth, even if that means accepting an offer of help from an unlikely source in Jen. As they track down Jack, the reality of Tasha's marriage is finally exposed.

Three years later, Tasha and Emily live in Cyprus under fake names. Jen plans her wedding, while Tasha discovers Jack's early prison release.

Jack is on the warpath and Jen attempts to warn Tasha, but she's too late. The three find themselves in a stand-off and only one person ends up with the gun.

As Jen is faced with an uncomfortable choice, Tasha's mission to be reunited with her daughter pushes her to further extremes. When a motorway accident leaves some battling for survival, others escape to a new life, free of the past.

Jen arrives in Cyprus to warn Tasha, but Tasha is determined to finally confront Jack. Unfortunately, Jack's earlier machinations come into play.

Jen sets Jack straight, meanwhile in Cyprus, Tasha is in a desperate situation. Sam works out where she is hiding and asks Jen for help.
