Clem has an emergency to deal with: her daughter is a victim of heavy metal poisoning. Time is of the essence. She's got to find out what caused the illness, and fast. Val, just as strong willed as his mother, takes an interest in ecology and gets a crush on a young activist named Clara. Izia is having a hard time fitting in at Marie-France and Michel's. Soon Victoire is the only one left she can count on to support her. Will the young couple survive their first real relationship crisis? Adrian, who for the time being has taken a job teaching salsa dancing, gets an indecent proposition. Hard to say no when you're broke and have a child to raise. Troubling times for Clem, who keeps fighting and knows she can count on Fred. But does she really know him for who he is?
