Plot "Big John" McMasters and "Square John"/"Shorty" Sand are two down-on-their-luck oil wildcatters who join forces. Without enough money, they steal drilling equipment from a skeptical Luther Aldrich. Their well proves a bust and they have to hastily depart when Aldrich shows up with the sheriff to take back his property. The two oilmen team up and make enough money to partially pay Aldrich.
