The 2 season of Mistresses was broadcast on BBC One from mardi 17 février 2009 to mardi 24 mars 2009. It consists of 6 episodes, the first one is called "Episode 1" and the last one "Episode 6".
Set in a world where friends are the new family, Mistresses follows the lives and loves of a close group of thirty-something girlfriends who met at university but whose lives have taken very different turns.
Each has a different experience of infidelity and love: bed-hopper, unwitting instigator, devoted mistress and wronged wife.
The tangled web of love and deceit envelops all four, with life-changing revelations which prove that life is not always greener on the other side. This is a story about secrets and anger, passion and lust, loss and guilt.
