There was a film shown on TV in England, it would have been late 80s or early 90s (around the time of untamed love, bringing home Andrew and the one with the boy who ends up on the kinetic diet). The only thing I remember about the film about the abducted boy, is the mother searching for him, and some scenes where he is sedated and in a cot, I think he was kept in a warehouse or some other abandoned place. I remember a woman who I think may have been the boys Grandmother I can’t remember. Please help me name the movie
