Foreign Bodies was the work of playwrights, Graham Reid, from Ulster, and Bernard Farrell, from Dublin; neither had experienced the hatred they were led to believe would greet them when they mixed with people from across the border, and this was the basis for their series. Roisin (Hilary Reynolds) and Septa (Maeve Germaine) are two young nurses from Dublin who go to work at a hospital in Belfast. Roisin meets and falls in love with Tom (Dan Gordon), a young Protestant car mechanic. This causes a series of problems for the young couple, their families and friends.
