**Abstract:**

Assume that $W : \mathbb R^m \to \mathbb R$ is a nonnegative potential that vanishes only on a finite set $A$ with at least two elements. By direct minimization of the action functional on a suitable set of maps we give a new elementary proof of the existence of a heteroclinic orbit that connects any given $a_-\in A$ to some $a_+\in A \setminus \{a_- \}$.
