An ill-fated first encounter brings Anna and Sam, two lonely neighbours who have each hit rock bottom, together in the most unexpected of ways, changing their lives forever.

Anna decides to grab life by the horns after a stark wake-up call from her doctor, while Sam strives to win back his wife. But when their worlds collide once again, will the spark between these two neighbours be reignited?

Anna is prepared to forgive and forget after their last uncomfortable encounter, but when she's inadvertently humiliated by Sam once again, she decides to step out of her comfort zone and embrace the world of online dating - with disastrous results.

Despite all the obstacles they've faced, Anna and Sam appear to be in a good place, but a surprise phone call changes everything. As they finally confront what they really mean to each other, they find the answers in unexpected places.

Shelley's unexpected visit sends Sam into a frenzy, and he turns to Anna for help. She's reluctant at first, but is left to pick up the pieces when Shelley delivers a devastating blow. And as the dust settles, events take a surprising turn.

When Anna reunites with a blast from her past, what begins as a fun reunion soon turns into a painful trip down memory lane. And having clearly lost his mojo, Sam is urged to try again with Shelley - but his return to the family home ends in chaos.
