Unable to pay rent and with debt collectors on his tail, Isa's crumbling career forces him to take on the mysterious murder case of a businessman.

After Refik witnesses Erkan shredding important paperwork, he pushes Isa to dig deeper. While Seda discovers that her wine stock has been vandalized.

When Isa wakes up disoriented from the night before, he starts to piece together a worrying chain of events — putting Seda at the heart of the crime.

With one eye on the enterprise and another on Seda, Erkan drags Isa's reputation through the mud. Meanwhile Seda is worried that Isa might need therapy.

Isa and Seda partner up to get to the bottom of things, when they find out that Erkan has been operating contraband shipments under Refik's name.

The police still don't consider Refik's death mysterious, despite Taygun's fate — but when Erkan shows up uninvited, Seda is more than ready for him.

Isa sees his father again, straddling the line between life and death. Crimes of passion bubble to the surface when the truth is finally revealed.
